Titanium is one of the most common metals applied in medicine. Wide use of titanium and its alloys as biomaterials stems from their lower elastic modulus, good fatigue strength and better corrosion resistance comparing with more conventional stainless steel and cobalt-based alloys. Titanium is generally biocompatible but it may release of dangerous metal ions causing eventual inflammation, failure and removal of implant. Besides, titanium has relatively poor tribological properties. For this reason, there is a great need for creating and using composite materials in medicine, which give possibility of optimizing mechanical and biological properties. In medical applications, metal-ceramic composite materials mainly consist of a metal matrix and ceramic particles as a reinforcement phase or metal coated with ceramics. In the present work, composites with particles of hydroxyapatite or silica combined with titanium matrix were prepared by the combination of mechanical alloying and powder metallurgical process. Mechanical properties and corrosion resistance of these composites were investigated. The results show an enhancement of properties in titanium-ceramic composites in comparison with polycrystalline titanium.
