Opis:: The aim of the present work was to plan and carry out an experiment consisting of amorphization of industrial magnesium alloy WE 43 (Mg - 4 Y - 3 RE - 0.5 Zr) modified by the copper addition. Investigated alloy modified with 20% of copper was rapidly quenched with the use of melt spinning technique. The effects of cooling rate on the structure and properties of the obtained material were extensively analyzed. The structure and phase analysis of samples were examined using X-ray diffraction method (XRD) while the thermal stability of the samples was determined by differential scanning calorimetry (DSC). Microstructure observations were also conducted. The microhardness tests (HV_0.02) and corrosion resistance tests were carried out to investigate the properties of the material. Corrosion resistance measurements were held using a typical three-electrode system. As the result of the research, the effect of cooling rate on microstructure and properties of investigated alloy was determined.

Opis:: Angular momentum pumps are very often applied onboard ships. These pumps are used in cooling circuits of medium and high power engines, power plant boilers and in bilge, ballast and fire installations. Very extensive use of angular momentum pumps on board is connected with their numerous advantages. During operation the wear of marine hull, the rotor and shaft seals take place. The research attempts to increase the service life of shafts. The article presents the research results referring to the analysis of the influence of finish treatment (lathing, grinding and burnishing) on the corrosion properties of steel applied to marine pump shafts. The research was performed on a roller of 40 mm in diameter made of X5CrNi18-10 (AISI 304 L) stainless steel. The lathing process was carried out by means of a WNMG WF 080408 Sandvik Coromant cutting tool with replaceable inserts. The grinding process was performed by grinding attachment for lathes. The 1 - 80x10x32 - 99C 80-N V grinding wheel was used for the process. The process of burnishing was done by SRMD burnisher by Yamato. In addition, the influence of the burnisher passes number on the corrosion properties was determined. The paper will present the results of electrochemical impedance spectroscopy research. To conduct the survey the Atlas 0531 EU and IA potentiostat was used. Determination of the corrosion process parameters was performed computer programs: AtlasLab 2.0 and EIS Spectrum Analyzer.

Opis:: In this study, to investigate effects of tin addition on the microstructures and corrosion properties, Zn-1Mg-xSn (x = 1.0, 2.0 and 5.0 wt.%) ternary zinc alloys were prepared. The experimental results indicated that the Zn-1Mg-2.0 wt.% Sn alloy has the better mechanical properties compared with pure zinc and Zn-1Mg alloy. The tensile strength of the alloy material is 173.2±3.7 MPa, the yield strength is 120.7±2.4 MPa, the elongation is 5.64±0.08% and the hardness is 76.9±0.8 HV. The average degradation rate of the alloys immersion in SBF solution for 60 days is 0.16±0.03 mm/year, and the Zn-1Mg-2.0 wt.% Sn alloy hemolysis rate is only 0.81±0.02%. It is confirmed that the addition of tin is effective to improve the mechanical properties and degradation of Zn-1Mg alloy. It may be a candidate of the clinical application requirements of the degradable implant materials in orthopedics.

Opis:: The impact of Garnet addition into the AL7075 aluminium matrix on the physical, mechanical and corrosion properties are studied in this research paper. Al 7075/garnet composites are fabricated by using two-stage stir casting method in different (0, 5, 10, 15) volume percentages. Photomicrograph of prepared samples revealed the uniform distribution of garnet reinforcement into the base matrix. The corrosion rate is calculated by potentiodynamic polarization method. The actual density is increased by around 1.2% for al 7075 / garnet (15%) composite as compared to base alloy. Micro hardness of al 7075 / garnet (15%) composite is raised by around 47 (34%) compare to as cast base matrix. Al 7075 / garnet (15%) composite tensile strength stood at 252 Mpa, which is 40% greater than the base alloy. Al 7075 / 15% garnet composites reduce around 97% of corrosion rate than the base matrix. Alloy elements influenced the corrosion than Garnet reinforcement.

Opis:: The secondary aluminium alloys are very important material in actual industry from economic and ecological point of view. The secondary aluminium used for production of casts, however, contains some elements, i.e. iron, – affecting physical, chemical and mechanical behaviour. The subject of our investigation has been corrosion behaviour in natural atmosphere of the hypoeutectic AlSi7Mg0.3 cast alloys with various content of iron, because the Fe content affects not only mechanical properties but corrosion resistance, as well. Three types of the AlSi7Mg0.3 cast alloys were exposed for 9 months in natural atmosphere and the measure of their degradation by corrosion was found by determination of the weight loss and the light microscopy. In addition, a scanning electron microscopy (SEM) analyses and evaluation of surface changes were used. The corrosion behaviour in natural atmosphere was compared to results of the carried out electrochemical and exposure laboratory experiments in chloride solutions.

Opis:: The aim of this paper was to investigate the corrosion resistance of Mg₆₆Zn₃₀Ca₄ and Mg₆₈Zn₂₈Ca₄ metallic glasses and evaluate the ability of this amorphous alloy use for medical applications as biodegradable medical implants. Taking into account the amount of Mg, Zn, Ca elements dissolved in multielectrolyte physiological fluid (MPF) from Mg₆₆+xZn₃₀-xCa₄ (x=0.2) alloys the daily dose of evolved ions from alloys components was determined. Additional goal of the paper was determination of corrosion rate (Vcorr) and amount of hydrogen evolved from amorphous magnesium alloys in simulated environment of human body fluids during 24h immersion and during electrochemical tests. Corrosion studies were done in the multielectrolyte physiological fluid (MPF) at 37°C. The amount of hydrogen evolved [ml/cm²] and corrosion rate Vcorr [mm/year] of amorphous Mg₆₆Zn₃₀Ca₄ and Mg₆₈Zn₂₈Ca₄ alloys were compared. The work also presents characterization of Mg-based bulk metallic glasses structure in the form of 2 mm thickness plates. Samples structure was analyzed by means of X-ray diffraction. Fracture and surface morphology of magnesium alloy samples were identified using scanning electron microscopy.

Opis:: Zbadano wpływ warstw TiO2 uzyskanych metodą zol-żel i wygrzanych w temperaturach 450oC i 800oC na właściwości korozyjne biomedycznego stopu Fe-Cr-Ni Rex 734 (ISO 5832/9). Badania wykonano w odtlenionym roztworze Tyrode’a w temperaturze ciała ludzkiego 37oC (310 K). Stwierdzono polepszenie właściwości korozyjnych stopu przez warstwy wygrzane w temperaturze 450oC i pogorszenie przez warstwy wygrzane w temperaturze 800oC. Przyczyną pogorszenia właściwości korozyjnych przez warstwy wygrzane w 800oC mogą być tlenki i węgliki metali będących składnikami stopu, które powstają w tej temperaturze. Potwierdziły to pomiary korozyjne stopu Rex 734 bez warstw TiO2, wygrzanego w takiej samej temperaturze.
The influence of TiO2 sol-gel layers heated at 450oC and 800oC on corrosion properties of biomedical alloy Fe-Cr-Ni Rex 734 (ISO 5832/9) was investigated. The investigations were carried out in deoxygenated Tyrode’s solution at human body temperature 37oC (310 K). It was found that the layers heated at 450oC improve corrosion features of this alloy on the contrary to the layers heated at 800oC. The reason for these worse corrosion features of layers heated at 800oC can be carbides and oxides of alloy components which were formed at this temperature. It was confirmed by corrosion measurements of Rex 734 alloy without TiO2 layers which was heated at the same temperature.

Opis:: Stopy kobaltu są materiałami wykorzystywanymi w medycynie oraz stomatologii ze względu na swoje idealne połączenie dobrych właściwości wytrzymałościowych, korozyjnych oraz biokompatybilność. Obecnie stopy kobaltu są jednymi z najbardziej atrakcyjnych materiałów metalowych, używanych do wyrobu implantów w tym: sztucznych stawów biodrowych, kolanowych, dysków miedzykręgowych, śrub zabezpieczających złamania. W stomatologii wykonuje się z nich wszelkiego rodzaju wkręty, stanowiące podstawę do przytwierdzania zębowych protez ceramicznych. Ze względu na powszechne wykorzystanie stopów kobaltu w stomatologii, w pracy podjęto badania elektrochemiczne wybranych stopów kobaltu: Co-Cr-Mo i Co-Cr-W, których celem było określenie właściwości korozyjnych podczas ekspozycji w fizjologicznym roztworze sztucznej śliny, w temperaturze 37 °C, pH = 8,3 i swobodnym dostępie tlenu.
Cobalt alloys are used in medicine and dentistry due to perfect combination of their high strength, corrosion resistance and biocompatibility. Currently, cobalt alloys are among the most attractive metallic materials used to manufacture such implants as artificial hip joints, knee joints, intervertebral discs, screws securing the fracture. All kinds of screws used in dentistry for basic fixing of ceramic dental prostheses are made from cobalt alloys. Widespread use of cobalt alloys in dentistry is the reason for electrochemical research on selected cobalt alloys (Co-Cr-Mo and Co-Cr-W). The aim of the research was to determine the corrosion when the alloy is exposed to physiological artificial saliva solution at the temperature of 37 °C, pH = 8.3 and in aerated solution.

Opis:: In this study, microstructure, mechanical, corrosion and corrosive wear properties of Mg-xAg the as-cast and extruded alloys (x: 1, 3 and 5 wt.%Ag) were investigated. According to the experimental results, as the amount of Ag added in the casting alloys increases, the secondary phases (Mg4Ag, Mg54Ag17) emerging in the structure have become more clarified. Furthermore, it was observed that as the amount of Ag increased, the grain size decreased and thus the mechanical properties of the alloys increased. Similarly, the extrusion process enabled the grains to be refined and the mechanical properties to be increased. As a result of the in vitro tests performed, the Mg-1Ag exhibited very bad corrosion properties compared to other alloys. On the other hand, according to corrosive wear tests results, a high wear rate and friction coefficient were found for Mg-5Ag alloys.

Opis:: In this article the structural and mechanical properties of grain refinement of Cu-Sn alloys with tin content of 10%, 15% and 20% using the KOBO method have been presented. The direct extrusion by KOBO (name from the combination of the first two letters of the names of its inventors – A. Korbel and W. Bochniak) method employs, during the course of the whole process, a phenomenon of permanent change of strain travel, realized by a periodical, two-sided, plastic metal torsion. Moreover the aim of this work was to study corrosion resistance. The microstructure investigations were performed using an optical microscope Olimpus GX71, a scanning electron microscope (SEM) and a scanning transmission electron microscope (STEM). The mechanical properties were determined with INSTRON 4505/5500 machine. Corrosion tests were performed using «Autolab» set – potentiostat/galvanostat from EcoChemie B.V. with GPES software ver. 4.9. The obtained results showed possibility of KOBO deformation of Cu-Sn casting alloys. KOBO processing contributed to the refinement of grains and improved mechanical properties of the alloys. The addition of tin significantly improved the hardness. Meanwhile, with the increase of tin content the tensile strength and yield strength of alloys decrease gradually. Ductility is controlled by eutectoid composition and especially δ phase, because they initiate nucleation of void at the particle/matrix interface. No significant differences in the corrosion resistance between cast and KOBO processed materials were found.

Opis:: Iron aluminides are iron-aluminum alloys that have excellent resistance to oxidation at high temperatures with low density, high resistance/weight ratio and a low manufacturing cost. Due to its characteristics, these alloys are presented as an option to replace stainless steels in certain applications. This works intends report the casting process and subsequent analyses involving microstructure, mechanical properties, and corrosion resistance of two Fe-Al-C alloys (Fe-11wt%Al and Fe-25wt%Al, containing 0.31-0.37%C), which were prepared in an induction furnace and poured in a permanent mold. Samples of these alloys were characterized and presented elevated hardness values of 37 HRC (alloy Fe-11wt%Al) and 49.6HRC (alloy Fe-25wt%Al) and microstructure with aluminides type Fe3Al and FeAl and also carbides type K. The Fe-11wt%Al alloy exhibited superior resistance to uniform corrosion, although both Fe-Al-C alloys exhibited significantly higher corrosion rates compared to a binary iron aluminide in 0.5M H2SO4 containing naturally dissolved oxygen.

Opis:: Duplex Stainless Steels (DSS) and Super Duplex Stainless Steel (SDSS) have excellent integration of mechanical and corrosion properties. However, the formation of intermetallic phases is a major problem in their usage. The mechanical and corrosion properties are deteriorated due to the presence of intermetallic phases. These phases are induced during welding, prolonged exposure to high temperatures, and improper heat treatments. The main emphasis of this review article is on intermetallic phases and their effects on corrosion and mechanical properties. First the effect of various alloying elements on DSS and SDSS has been discussed followed by formation of various intermetallic phases. The intermetallic phases affect impact toughness and corrosion resistance significantly. Their deleterious effect on weldments has also been reviewed.

Opis:: The main objective of this paper is to present a comparison of the corrosion inhibiting effect of thiourea and THAM (tri(hydroxymethyl)aminomethane) on carbon steel samples immersed in calcium chloride solutions. The testing has shown that to inhibit the corrosive action of the calcium chloride solution, the thiourea solution can be successfully replaced by the THAM solution. The study was performed with the use of st3s, structural and reinforcing steel. In the case of st3s steel samples, the application of the 0.01% THAM solution causes a decrease of its weight loss by about 60%. The application of a 10-times stronger THAM solution causes an increase of the corrosion inhibition on the tested samples by about 20%. A combined protective action of the thiourea and THAM solutions brings about an increase of the corrosion process inhibition by about 70% both for the st3s and the structural samples. The 0.01% and 0.1% THAM solutions applied to inhibit the corrosion process on structural samples cause an increase of the corrosion protection by about 50% and 15% respectively.

Opis:: The AISI 316L type steel belongs to the group of chromium-nickel stainless steels. They are determined according to European standards as X2CrNiMo17-12-2 and belong to the group of austenitic stainless steels. Steels of this group are used for elements working in seawater environments, for installations in the chemical, paper, and food, industries, for architectural elements, and many others. The chemical composition of corrosion-resistant austenitic steels provides them with an austenite structure that is stable in a wide temperature range, under appropriate conditions for heating, soaking, and cooling. 316L steel plate was subjected to a technological treatment of hot straightening with an oxyacetylene torch, which is not commonly used for this type of steel, mainly due to the lack of objective assessment of whether the austenitizing temperature has been achieved and the stability of the heat treatment process is ensured. The single-phase structure of austenite with high corrosion resistance, without precipitation of carbides, steel is obtained by supersaturation in water from 1100°C. The purpose of the presented research was to determine the usefulness of the flame straightening process for a ship structure made of 316L steel.

Opis:: The paper presents a study on corrosion behaviour and tribological properties of nickel composite coatings deposited by electrochemical method on aluminium alloy from 2xxx series (AlCu₄MgSi). The nickel composite coatings were produced in a Watts bath of the following chemical composition: NiSO₄·7H₂O 150 g/l, NiCl₂·6H₂O 30 g/l, H₃BO₃ 30 g/l with the addition of saccharin in an amount of 2 g/l. As hard ceramic dispersed particles embedded in the coating, alumina (Al₂O₃) was used in an amount of 12,5; 25; 50 and 75 g/l. Coatings were produced using cathodic current density of 6 A/dm2, bath temperature of 60°C, pH 4, and the time 60 minutes. The electroplating bath was stirred with a mechanical stirrer (350 rpm). The results obtained were compared with a nickel coating deposited without the ceramic particles. It was found that the presence of Al₂O₃ increases the wear resistance of composite coatings, but does not significantly improve the corrosion properties.

Opis:: The aim of this paper was to analyze the impact of varying zirconium addition on selected properties of AlSi5Cu2Mg alloy. The results of this research showed that zirconium addition in the range of 0.05 to 0.20 wt. % caused a decrease in ultimate tensile strength and yield strength of the experimental alloys after T7 heat treatment, probably due to the formation of primary Al3Zr intermetallic phases. These phases were observed as an individual plates or as a formation of two crossed plate-like phases. Potentiodynamic polarization tests in 3.5% NaCl solution revealed that addition of Zr had a positive effect on thermodynamic corrosion stability of the AlSi5Cu2Mg alloy due to shift of the corrosion potential to a more positive values for all as-cast samples. Addition of Zr in the as-cast alloys improved corrosion kinetics by lowering of corrosion current density.

Opis:: The article presents the results of the mechanical properties of aluminium alloy AW 5059 [AlMg5.5Zn] welded by MIG and friction stir welding FSW. Friction Stir Welding (FSW) – a new technology can be successfully used for butt welding of different types of aluminium alloy sheets. Research results on stress corrosion cracking for the AW 5059 alloy welded joints are presented. Stress corrosion cracking was examined via the slow-strain-rate-testing (SSRT) according to EN ISO 7539-7. The following parameters were measured: time-to-failure, obtained max. load, strain energy (the diagram surface under the stress-elongation curve), relative elongation of the specimen, tensile stress and reduction-in-area. The fractures were analysis by scanning electron microscope of Philips XL 30 type. Tests were carried out in the air and in a 3.5% water solution of NaCl – artificial sea water. On the basis of obtained test results, it can be said that 5059 alloy joints welded by FSW are resistant to stress corrosion in sea water. Tests have shown that the 5059 alloy, welded by FSW, has superior strength properties compared to the FSW 5083 alloy, along with comparable, good resistance to stress corrosion. Original value are received results of the mechanical and corrosion properties of a new method friction stir welding used for joining AW 5059 alloy sheets.

Opis:: Sliding wear properties and corrosion resistance in Ringer’s solution of uncoated and diamond-like carbon (DLC) coated X46Cr13 steel was tested. The Raman spectra showed that the DLC film was successfully coated by plasma assisted CVD method onto the steel surface. The wear test, carried out using a ball-on disk tribometer, revealed that the DLC coating show better resistance to sliding wear and lower friction coefficient against a 100Cr6 steel ball than five times softer X46Cr13 steel. The oxidation kinetic parameters were determined by means of both the gravimetric and electrochemical method. It was found that the DLC coating markedly decreased the rate of corrosion of the X46Cr13 steel, irrespective of the corrosion mechanism involved.

Opis:: This paper systematically investigated the effects of normalizing, annealing and water-quenching heat treatments on corrosion of samples of the steel types in 0.5M H2SO4 containing 3.5%-Wt sodium chloride at ambient temperature. Non-heat-treated (control) and heat-treated samples of low and medium carbon steel with respective carbon contents of 0.207% C and 0.46% C were produced, cleaned, weighted and immersed in pairs in the chloride medium for various durations of 72, 96 and 168 hours. Thereupon, the samples were removed, re-cleaned, dried, and re-weighed. The respective average pair weight losses were evaluated and used to determine the corrosion penetration rates of the samples in the medium. Analysis of the entire obtained rates data showed that corrosion of the samples tended to increasingly passivate with the exposure time in all cases. The low carbon steel samples generally showed much less resistance to corrosion in the medium, compared to the medium carbon steel. The experiment demonstrated that the control, annealed, normalized, and quenched low carbon steel samples comparably resisted corrosion in the medium. Furthermore, the quenched medium carbon steel samples exhibited much better corrosion resistance than their annealed and the annealed better than their normalized. Correlative micro-structural analysis of the control, normalized, annealed, and quenched steel types with the worst-case corrosion showed no appreciable changes in the case of low carbon steel samples, but various levels of reduction and re-orientations in grain sizes and inter-granular boundaries of the carbide, ferrite, pearlite, and martensite in the matrix structures of the medium carbon steel samples, compared to the corroded control samples of the steel types.

Opis:: Due to the complexity of the marine environment, in deep-sea drilling, all kinds of strings are corroded by different deepsea conditions for a long time, accompanied by high temperature and high pressure, which lead to the continuous change of mechanical properties of materials. In order to solve the problem that the material mechanical parameters cannot be accurately described in the performance analysis of the casing, deep-sea simulated corrosion and material damage experiments of P110 material were carried out in this paper. Mass loss and tensile experiments on corrosion-damaged test pieces were conducted under different corrosion experimental periods. The changes in mechanical properties of the material were analyzed. Equations of the variation of the equivalent yield strength and the equivalent tensile strength were obtained. The results show that the equivalent yield strength and the equivalent tensile strength decrease with the increase of the weight loss rate. Based on the experimental results and finite element analysis, a method for establishing the material corrosion model was proposed in this paper. The deep-sea drilling corrosion performance model of P110 material was established, which greatly reduced the error caused by the material uniformity assumption in finite element analysis. This paper provides a theoretical basis for the analysis of reliability and life of P110 materials in wells.

Opis:: Friction welding associated with mixing the weld material (FSW - Friction Stir Welding ) is an alternative to MIG and TIG welding techniques for Al-alloys. This paper presents experimental results obtained from static tension tests on specimens made of AW-7020M and AW-7020 alloys and their joints welded by using FSW method carried out on flat specimens, according to Polish standards : PN-EN ISO 4136:2011 and PN-EN ISO 6892-1:2010. Results of corrosion resistance tests are also presented. The tests were performed by using the electrochemical impedance spectroscopy (EIS). EIS measurement was conducted with the use of three-electrode system in a substitute sea water environment (3,5% NaCl - water solution). The impedance tests were carried out under corrosion potential. Voltage signal amplitude was equal to 10mV, and its frequency range - 100 kHz ÷ 0,1 Hz. Atlas 0531 EU&IA potentiostat was used for the tests. For the tested object an equivalent model was selected in the form of a substitute electric circuit. Results of the impedance spectroscopy tests are presented in the form of parameters which characterize corrosion process, as well as on Nyquist’s graphs together with the best-fit theoretical curve. Analysis of the test results showed that the value of charge transfer resistance through double layer , Rct , for the FSW- welded specimen , was lower than that for the basic material, and that much greater difference was found in the case of AW-7020M alloy. The impedance spectroscopy tests showed that both the FSW-welded joints and basic material of AW-7020M and AW-7020 alloys were characterized by a good resistance against electrochemical corrosion in sea water environment , and that FSW –welded joints revealed a greater corrosion rate. The performed tests and subject-matter literature research indicate that application of FSW method to joining Al-alloys in shipbuilding is rational.
