摘要：
Alloys of titanium with 20-22 at. % niobium and 12-13 at. % zirconium. The alloys are prepared by mechanical alloying of elemental powders and densification by spark plasma sintering. The alloys have a nano-scaled, equiaxed granular structure, a microhardness of at least 650 HV and a modulus of 90-140 GPa. The inventive alloy is corrosion resistant, biocompatible, and is of a higher wear resistance and durability compared to the Ti-6Al-4V alloy. The bioactive surface of the inventive nanostructured alloy promotes a higher protein adsorption that stimulates new bone formation than other titanium-based alloys. These alloys are suitable for various biomedical and dental applications.
