Development of Ti–Zr alloys by powder metallurgy for biomedical applications

Commercial pure titanium offers excellent biocompatibility, but its properties are poor for some biomedical applications where both mechanical and biocompatibility required. The study attempts to evaluate the developement ofTi–Zr alloys using conventional powder metallurgical techniques by mixing elemental (BE) or (MA) as a function of zirconium content (6, 15 20 wt-%). Sintering was performed at 1523 K after compaction 700 MPa BE powders 900 MA powders. Sintered parts were tested obtain maximum flexural strength. Samples characterised microstructurally X-ray diffraction phases. Optical microscopy (OM) scanning electron (SEM) phases, porosity, grain size. Flexural strength Ti CP greater, slightly diminished with increasing Zr content. However, elastic modulus increased compared Ti. results obtained show that it is possible make these metallurgy.
