Advances in Materials Science
EN The titanium and its alloys are potentially prone to hydrogen embrittlement, including those proposed for dental implants. The research has been aimed to assess a susceptibility to environment-enhanced degradation of the Ti-13Zr-13Nb alloy in artificial saliva with or without hydrofluoric acid, subj[...]

PL W artykule zaprezentowano badania procesu szlifowania stopów tytanu ściernicami z elektrokorundu chromowego, węglika krzemu, cBN oraz GP. Podczas szlifowania płaszczyzn zastosowano glikol propylenowy i handlowe płyny obróbkowe, podawane z minimalnym przepływem do strefy skrawania. Wyniki badań odnie[...]
EN The results of studies of the grinding process of titanium alloys by the grinding wheels with chrome electrocorundum aluminum oxide, silicon carbide, CBN and GP were presented in the article. During the grinding of surfaces propylene glycol and commercial cutting fluids were applied, dedicated used [...]

EN The characteristic features of surface cracking observed after laser melting with CO2 and Nd:YAG laser were described. The cracks were always present, their length approaching some part of melted zone and scarcely dependent on laser melting conditions. The appearance of cracks was attributed mainly [...]

EN Many titanium alloys and even materials such as concrete exhibit a nonlinear relationship between strain and stress, when the strain is small enough that the square of the norm of the displacement gradient can be ignored in comparison to the norm of the displacement gradient. Such response cannot be[...]

EN 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 Rin[...]

EN The laser remelting of the Ti6Al4V alloy was made on specimens pre-heated at elevated temperatures. The laser treatment effected in change of microstructures of surface layers and an appearance of blisters and numerous cracks. The corrosion tests demonstrated the decrease in corrosion resistance for[...]

EN Titanium alloys used in medical applications (especially dentistry) are exposed to the actions of various compounds that appear periodically in the mouth. Fluorine compounds are dangerous for the surface of titanium alloys, because they generate a dissolution of the passive layer. In this way, they [...]

Machine Dynamics Problems
EN The article deals with possibilities of preparation of titanium alloys based on intermetallic phases from the system Ti-Al. Production of the TiAl alloys is difficult because of the reactivity of titanium. Therefore the alloys were prepared in plasma furnace and vacuum furnace. The preparation by th[...]
