Abstract
Legure titana, zbog svojih povoljnih svojstava, pronalaze sve veću primjenu u biomedicini. Međutim, zbog njihove visoke cijene, danas se sve više razvijaju i koriste nove metode s ciljem proizvodnje ekonomičnijih legura. Stoga je u okivru ovog rada za proizvodnju legure Ti80Nb20 korištena tehnologija metalurgije praha. Istraživana titan-niobij legura pripravljena je iz elementarnih prahova miješanjem odnosno mehaničkim legiranjem u kugličnom mlinu. Nakon toga je iz smjese izdvojeno 8 uzoraka koji su prešani na hidrauličnoj preši, te sinterirani u cijevnoj peći u zaštitnoj atomsferi argona. Mikrostruktura sinteriranih uzoraka je karakterizirana različitim metodama kako bi se utvrdili optimalni tehnološki parametri za postizanje mikrostrukture sa zadovoljavajućim karakteristikama za primjenu u biomedicini. Dobiveni rezultati pokazuju da je uz malu korekciju primijenjenih tehnoloških parametara, u smislu produžavanja vremena miješanja/mehaničkog legiranja, primijenjenom tehnologijom metalurgije praha moguće ekonomično proizvesti Ti80Nb20 leguru sa svojstvima povoljnim za biomedicinsku primjenu.
Abstract (english)
Due to their favourably properties, titanium alloys are increasingly used in biomedicine. However, because of their high cost, new methods are being developed and used today to produce more economical alloys. Therefore, in the frame of this work, powder metallurgy was used to produce Ti80Nb20 alloy. The investigated titanium-niobium alloy was prepared from elemental powders by mixing i.e. mechanical alloying in a ball mill. After that, 8 samples singled out from the mixture were pressed on a hydraulic press and sintered in a tube furnace in a protective atmosphere of argon. For the characterization of the microstructure of sintered samples various methods were applied to determine the optimal technological parameters for achieving microstructure with satisfactory characteristics for biomedical applications. The obtained results show that with a small correction of the applied technological parameters, in terms of time extension of mixing/mechanical alloying, it is possible to economically produce Ti80Nb20 alloy with properties suitable for biomedical application by using powder metallurgy technology.
