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.
