Opis:
Sintered ferrous components were coated with electrochemical chromium coatings modified with nanodiamond particles. The nanodiamond particles were produced by detonation synthesis with an average grain size 8 nm. The objective of this study was to determine the tribological properties and the corrosion resistance of sintered iron samples coated with an electrochemically deposited chromium layer modified with nanodiamond particles. The thickness of the obtained composite coatings was more than 25 μm. The microstructure and microhardness were determined by metallographic methods. The mechanical and chemical properties of the samples were compared to uncoated samples prepared from the same iron powder. The microhardness was 5 times higher, the wear resistance increased 6 times and the corrosion resistance in 0.1 M NaCl solution was 10 times higher.

Opis:
This work aims at physico-mechanical properties of the Ti-containing chromium-free conversion coatings on zinc coated steel. The wear resistance of the whole conversion coating/zinc coating system depends on the deposition time of these coatings. As the duration of the deposition of conversion coatings containing titanium increases, the wear resistance of the samples decreases. The reason for this deterioration in wear resistance is likely worse adhesion of these coatings obtained at longer deposition times. The best adhesion to the zinc substrate posses coatings deposited for 20 s.

The paper presents the results of studies of hybrid composite layers Ni/Al2O3/Cgraphite produced by the electrodeposition method. Three variants of hybrid composite layers were prepared in electrolyte solutions with the same amounts of each dispersion phases which were equal to 0.25; 0.50 and 0.75 g/dm3. The structure of Ni/Al2O3/Cgraphite layers as well as the Al2O3 and graphite powders, which were used as dispersion phases was investigated. The results of morphology and surface topography of produced layers are presented. The modulus of elasticity and microhardness of the material of produced layers were determined by DSI method. Tribological and corrosion resistance tests of produced layers were carried out. Realized studies have shown that the material of the produced layers is characterized by a nanocrystalline structure. Incorporation of dispersion phases into the nickiel matrix increases the degree of surface development of layers. Ni/Al2O3/Cgraphite layers are characterized by high hardness and abrasion resistance by friction, furthermore, they provide good corrosion protection for the substrate material.

Opis:
This paper presents the results of oxidation andcorrosion tests carried out on titanium alloy Ti13Nb13Zr. The oxide film was prepared by electrochemical environment 2MH3PO4 for 30 min and 1h, at a constant voltage 40 V. The tests of corrosion resistance were performed by potentiostatic method in Ringer’s solution at different pH values : 7, 5 and 3. The change in an appearance of surface and the increase in corrosion resistance even in an acidic environment is an evidence that the electrochemical treatment of theTi13Nb13Zr alloy results in formation of dense, compact and likely amorphous oxide layer.

Opis:
The paper presents the influence of mechanical surface damage on the physicochemical properties of plates after implantation made of CrNiMo stainless steel, used in the treatment of anterior surface deformity of the chest. Analysis of the data allowed us to investigate the effect of implant design and condition of their surface on the results of chest deformation treatment. Results of electrochemical, impedance and surface wettability tests and SEM observations were compared with clinical observations. When removing the plates we found only slight inflammatory-periosteal reactions. On the basis of obtained results, it can be stated that plates, in spite of mechanical damage of the surface, were characterized by good corrosion resistance, a fact which is confirmed by the results of clinical evaluation.

Opis:
The parameters of heat treatment of Al-Zn-Mg alloys subjected to precipitation hardening have a substantial impact on mechanical and corrosion resistance. The rate of cooling after supersaturation, along with the ageing temperature and time, affect significantly mechanical properties of these alloys. The type of ageing (artificial or natural) after saturation implies corrosion resistance in seawater. Being a modification of the AlZn5Mg1 alloy, denoted as PA47, the AlZn5Mg2CrZr alloy reveals best mechanical properties among all aluminium alloys in shipbuilding [1]. However, the higher level of precipitation hardening, the higher susceptibility to corrosion, in particular to stress corrosion cracking (SCC). Describing the structure of Al-Zn-Mg alloys by identifying the precipitation free zone (PFZ) and the Guinier-Preston (G-P) zones provides the information on the corrosion resistance of these alloys.

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:
Porous hydroxyapatite doped SiO2 coatings were electrophoretically deposited (EPD) on commercially pure titanium. The influence of EPD parameters on coatings quality was investigated. Microstructural observation was done using transmission and scanning electron microscopy as well as X-ray diffractometry. The coatings consisted of spherical micro and nanocrystalline hydroxyapatite (HAp) as well as amorphous SiO2 nanoparticles. The coatings exhibited open porosity with pore diameter up to 1 μm and due to presence of nanoparticles high surface development. It was found that application of SiO2/HAp coating increase corrosion resistance of titanium in Ringer’s solution.

Opis:
The Ti15Mo alloy has been studied towards long-term corrosion performance in saline solution at 37°C using electrochemical impedance spectroscopy. The physical and chemical characterization of the material were also investigated. The as-received Ti15Mo alloy exhibits a single β-phase structure. The thickness of single-layer structured oxide presented on its surface is ~4 nm. Impedance measurements revealed that the Ti15Mo alloy is characterized by spontaneous passivation in the solution containing chloride ions and formation of a double-layer structured oxide composed of a dense interlayer being the barrier layer against corrosion and porous outer layer. The thi ckness of this oxide layer, estimated based on the impedance data increases up to ~6 nm during 78 days of exposure. The obs erved fall in value of the log|Z|f=0.01 Hz indicates a decrease in pitting corrosion resistance of Ti15Mo alloy in saline solution along with the immersion time. The detailed EIS study on the kinetics and mechanism of corrosion process and the capacitive behavior of the Ti15Mo electrode | passive layer | saline solution system was based on the concept of equivalent electrical circuit with respect to the physical meaning of the applied circuit elements. Potentiodynamic studies up to 9 V vs. SCE and SEM analysis show no presence of pitting corrosion what indicates that the Ti15Mo alloy is promising biomaterial to long-term medical applications.

Opis:
There are presented the results of researches conducted on the steel cast with surface alloy layer in this work. The measurement of the thickness, hardness and abrasion wear resistance was conducted in accordance with norm ASTM G 65-00. The measurement of the corrosion resistance was conducted in accordance with the potentio - dynamical method. It is shown that it is possible to obtain the alloy surface layer of different thickness by control of some factors: pouring temperature Tzal , diameter of grain of FeCrC alloy Zw and the thickness of the cast wall gśo. It is proved that the smaller diameter of ferrochromium grain, the thicker surface alloy layer. It is also said that the higher pouring temperature and thicker the cast wall, the thicker surface alloy layer. What is more - the smaller thickness of the cast wall, the bigger hardness and abrasion wear resistance.
W artykule przedstawiono wyniki badań odlewu staliwnego z powierzchniową warstwą stopową. Badania obejmowały pomiar grubości, twardości, odporności na zużycie ścierne wykonane zgodnie z normą ASTM G 65-00 oraz odporności na korozję metodą potencjo-dynamiczną. W wyniku przeprowadzonych badań stwierdzono, że sterując w zadanym zakresie zmiennymi czynnikami procesu takimi jak temperatura zalewania staliwa Tzal, średnica Zw ziarna stopu Fe-Cr-C i grubość ścianki odlewu gśo. można uzyskać powierzchniową warstwę stopową o różnej grubości. Wyniki badań dowiodły również, że stosowanie na wkładkę stopową żelazochromu o mniejszej średnicy ziarna powoduje powstanie powierzchniowej warstwy stopowej o większej grubości, podobnie jak przy wzroście temperatury zalewania i grubości ścianki odlewu. Ponadto stwierdzono, że im mniejsza grubość ścianki odlewu tym uzyskuje się większą twardość warstwy i odporność na zużycie ścierne.

The paper presents the study results of macro- and microstructure, microhardness and corrosion resistance of C45 medium carbon steel and CT90 high carbon steel after diffusion boriding and laser modification by diode laser. It was found that the increase of carbon content reduced the thickness of boronized layer and caused change in their morphology. Diffusion boronized layers were composed of FeB and Fe2B iron borides. As a result of laser surface modification of these layers, the microstructure composed of three areas: remelted zone, heat affected zone (HAZ) and the substrate was obtained. Microhardness of laser remelting boronized layer in comparison with diffusion boronized layer was lower. The presence of HAZ was advantageous, because mild microhardness gradient between the layer and the substrate was assured. The specimens with laser boronized layers were characterized by better corrosion resistance than specimens without modified layer.

The effect of heat treatment of the plastically worked 7000 series Al-Zn-Mg aluminium alloy system on its stress-corrosion resistance is examined. For the same chemical constitution, the effect of heat treatment on mechanical and corrosion properties of Al-Zn-Mg alloys systems is remarkable. It was proved that a parameter having significant effect on corrosion properties of the alloy is the rate of alloy cooling after heat treatment. This conclusion is confirmed by observation of structural forms which fully reflect mechanical and corrosion properties of the alloy.
