Mechanical Property and Microstructure of Ti-Ta-Ag Alloy for Biomedical Applications

Ti and some of its alloys (e.g. Ti–6Al–4V alloy) have become the metals of choice for the endosseous parts of presently available dental implants. In the present study, Ti-Ta-Ag alloys with a different Ag content were prepared using vacuum sintering (VS) and spark plasma sintering (SPS) process. The microstructure and mechanical properties of the Ti-Ta-Ag alloys were investigated. The results show that dense Ti-Ta-Ag alloys prepared using the SPS process exhibit high hardness and a suitable elastic modulus for implant materials for load-bearing applications. The effect of preparation methods on the microstructure of Ti-Ta-Ag alloys is discussed.

This paper aims to investigate effect of spark plasma sintering temperature on mechanical property of Ti + ZrO2. The samples were prepared by SPS system with the different sintering temperature containing 900, 1,000, and 1,100 oC under the pressing pressure of 30 MPa in vacuum. The results show that hardness of Ti + 2 wt.% ZrO2 alloy increases with increasing sintering temperature. The highest hardness was 363 HV while suitable temperature for sintering Ti + 2 wt.% ZrO2 alloy was 1,100 oC. Further, the microstructure and crystal structure of all samples were single-α-phase structure with different in elements dispersion, which was related to amount of lattice expansion in the HCP structure.

This study aims to investigate the microstructure and mechanical properties of Ti-ZrO2 composites and ZrO2/Ti functionally graded materials (FGMs) fabricated by spark plasma sintering (SPS). SPS has been conducted in a vacuum at 1400 oC under the uniaxial pressure of 30 MPa. Mechanical properties such as hardness and elastic modulus of Ti-ZrO2 composites have been systematically investigated using micro-Vickers and nanoindentation. The experimental results demonstrate that the mechanical properties of Ti are dramatically improved by an addition of small amount of ZrO2. There is almost no effect from the presence of Y2O3 in ZrO2 on the hardness of Ti-ZrO2 composites. ZrO2/Ti FGMs have been successfully fabricated, and mechanical properties of the FGMs have been examined.
