Abstract
Porous titanium-based alloys are very promising materials for medical implants due to their low density and easy osseointegration. In addition, proper porosity and pore size allow adjusting the mechanical properties of implants to values closer to human bone. The aim of this work is to prepare porous metallic biomaterials based on Ti-Si alloys with defined porosity for surgical and dental applications. Alloys were prepared by powder metallurgy using reactive sintering. Best results reached TiSi5 and TiSi10 alloys. The TiSi5 alloy contains smaller pores and achieves lower porosity values. This alloy also has the highest yield strength in compression from these alloys. On the other hand, the TiSi10 alloy is more porous and it is likely to be more suitable for osseointegration.
