Abstract

Karakterizacija legure titana s dodatkom bakra za biomedicinske primjene uključuje sveobuhvatnu procjenu svojstava materijala i prikladnosti za upotrebu. Legure titana često se biraju zbog njihove biokompatibilnosti i mehaničkih svojstava, dok se bakar može dodati radi poboljšanja specifičnih karakteristika poput antibakterijskog djelovanja. Glavni cilj ovog rada je konvencionalnim postupcima metalurgije praha proizvesti leguru titana s dodatkom 8% bakra koja bi imala biomedicinsku primjenu, a učinak procesnih parametara, kao što su vrijeme miješanja i tlak prešanja, na mikrostrukturne karakteristike proizvedene legure procijeniti korištenjem odgovarajućih metoda. Rezultati provedenih istraživanja pokazuju da je korištenjem metalurgije praha moguće proizvesti kompaktnu titan-bakar leguru, uz dodatno podešavanje procesnih parametara. Poglavito se to odnosi na vrijeme miješanja elementarnih prahova.

Abstract (english)

The characterization of a titanium alloy with added copper for biomedical applications requires a comprehensive evaluation of its material properties and suitability for use. Titanium alloys are often selected for their biocompatibility and mechanical properties, while copper can be added to enhance certain properties such as antibacterial activity. The main objective of this work is to apply conventional powder metallurgy techniques to produce a titanium alloy with 8% copper addition for biomedical applications. The effects of processing parameters such as mixing time and compaction pressure on the microstructural properties of the produced alloy are evaluated using appropriate methods. The results of the research carried out show that it is possible to produce a compact titanium-copper alloy using powder metallurgy, but that it is necessary to adjust processing parameters, especially the mixing time of the starting powders.
