Abstract

Titanium- and nickel-based alloys find a wide application in implantology and dentistry. Here we demonstrate the possibilities and advantages of powder metallurgy (PM) for the synthesis of these alloys. Using metal powders as reagents and specific operations such as cold pressing and sintering, traditional metallurgical processes have been avoided. PM gives the possibility for application of mechanochemical methods in obtaining amorphous or nanostructured products. In this work, the TiNi alloy is obtained by the mechanical alloying (MA) method. The structural and mechanical characteristics of the Ti-Ni alloy, suitable for human implants, and the Ni-Cr alloy, designed for metal-to-ceramic dental constructions, are studied in the present paper..
