Abstract: Ti-6Al-4V alloy is mostly used for dental and hard tissue implants, due to its high strength to weight ratio, high corrosion resistance, and relatively low elastic modulus. However, apart from health concerns of V ions release and higher Young’s modulus (~120 GPa) than human bone (~30 GPa), recent research indicates day-to-day cyclic loading instead of a single-load event such as a fall, might be the consequence of inherent stiffness of fixation implants.

Abstract: We investigate the new alloys of Mg–Ga–Zn–X system, where X = Ca, Y and Nd. These alloys can be used as biodegradable materials due to the low cytotoxicity of Zn and Ga and effectiveness of Ga against bone resorption, osteoporosis and Paget’s disease. [..] Read more

Abstract: Steel reinforcement of concrete structures is normally passivated due to high pH value of concrete interstitial electrolyte (pH 13-14). However, chloride contamination (e.g. [..] Read more

Abstract: The durability of reinforced concrete structures is limited mainly by the reinforcement material, as which a carbon steel is widely used. Carbon steel corrosion rate increases due to carbonation or contamination with chloride anions. [..] Read more

Abstract: The corrosion behaviour of four grades of valves steels i.e.; X33CrNiMn23-8, X50CrMnNiNbN21-9, X33CrNiMnN23-8, X50CrMnNiNbN21-8, X53CrMnNiN20-8 and X55CrMnNiN20-8 in combustion gases of fuel oil with different quantities of FAME (Fatty Acid Methyl Esters) has been studied. In this work, the results of kinetic oxidation of above mentioned valve steels in combustion gases from diesel engine with 5, 10, 20% [v/v] of FAME are presented. [..] Read more

Abstract: Supercritical water (SCW) is a promising medium with a broad spectrum of potential applications in the industry. However, the absence of appropriate structural material able to withstand the severe corrosive conditions of SCW still limits its utilization. [..] Read more

Abstract: In study the effect of the of Nd-(Fe,Co)-B particles biencapsulation method on bonded magnetic material atmospheric corrosion behavior has been evaluated. Bonded magnets were prepared from Nd12Fe77Co5B6 magnetic powder after biencaspsulation. [..] Read more

Abstract: The trend to use modern materials and technologies in the development and construction of rail vehicles leads to testing new suitable alternatives for surface treatment of strain parts. Within the research project, suitable thermally sprayed coatings as alternatives for former surface treatment of selected components of rail vehicles are tested. [..] Read more

Abstract: The possible differences in the protective performance of Zn and MIO pigmented epoxy coatings for different times of exposure performed during 533 hrs in 0.05 M NaCl were confirmed by new interpretation of ENA data in combination with single frequency (1 kHz) impedance test results. By this approach changes of resistivity and dielectric constant (identified on tested coating system at different times of exposure) can be related to delamination tendency as well as changing possibilities for new defects formation in tested type of coating for different time of exposure..

Abstract: The aim of the present study was to investigate the effect of the concentration of precursors in the reaction mixture on the microstructure and electrochemical corrosion properties of MgAl-LDH coatings deposited on magnesium alloy AZ31. The concentrations of precursors Mg(NO3)2 and Al(NO3)3 were set to 0.10, 0.05, and 0.02 M and 0.10, 0.05, and 0.02 M, respectively. [..] Read more

Abstract: The present work aims to investigate the characteristics of high temperature vacuum brazed WC-Co-NiCrBSi coatings deposited on 16MnCr5 steel substrate. The coatings characteristics like morphology, microstructure, chemical composition and the appearance of the interface with the substrate have been analyzed by means of Scanning Electron Microscopy (SEM) combined with energy-dispersive X-ray spectroscopy.

Abstract: The purpose of the work was to assess the influence of the vibro-abrasive treatment on the quality of the zinc coating. The use of vibro-abrasive finishing in the production process of fittings for overhead power line is designed to improve the aesthetics of the coating by eliminating zinc beads and burrs, as well as shorten the time of detecting the details on the production.

Abstract: In recent years, the cerium-based conversion coatings have been increasingly used as one of the more promising chromate coatings substitutes on aluminum alloys, as cerium compound do not pose environmental problems and the coatings provide an efficient corrosion protection close to that of chromium. The cerium-based layer was prepared from simple immersion of aluminium alloy sheets in a solution composed of a 4 - 8 g·L-1 Ce(NO3)3·6H2O; 30 - 50 ml·L-1 H2O2 (37 %) and 0.5 - 1,5 g·L-1 tannin at room temperature.

Abstract: It is generally recognized that the high content of non-metallic inclusions in structural steels alter their physical and mechanical properties. Formation of non-metallic inclusions is a complex phenomenon that depends on the composition, pressure and temperature of the working media. [..] Read more
