Abstract

Titan i njegove legure najzastupljeniji su materijali u izradi implantanata za medicinske svrhe zbog dobrih mehaničkih svojstava, biokompatibilnosti i kemijskih svojstava. Glavni i veliki problem je znatno veći modul elastičnosti nego kod kosti zbog kojeg dolazi do efekta prigušenja opterećenja i propadanja kosti. Potreba zaštitne atmosfere kod lijevanja titana predstavlja još jedan problem. U ovom radu se istražuje mogućnost izrade titanij – magnezij metalnog kompozita. Zbog udjela magnezija smanjit će se gustoća, modul elastičnosti i poboljšati oseointegracijska svojstva. Kompozit će se izraditi metalurgijom praha postupkom hladnog izostatskog prešanja.

Abstract (english)

Titanium and its alloys are the most common materials in the manufacture of implants for
medical purposes due to their good mechanical properties, biocompatibility and chemical
properties. The main and big problem is the significantly higher elasticity modulus than that of
bone, which causes the stress-shielding effect and bone decay. The need for a protective
atmosphere in titanium casting is another problem. Titanium-magnesium composite will be
developed in this paper. Due to the content of magnesium, the density and modulus of elasticity
will decrease and the osseointegration properties will improve. The composite will be produced
by powder metallurgy using a cold isostatic pressing process.
