Advanced composite material: effect of composite SiC on compressive strength and hardness of porous titanium

Abstract

Porous titanium is an excellent bone-implant biomaterial. This article uses SiC as a reinforcing agent to compound into porous titanium materials to improve the mechanical properties of porous titanium as medical materials. Porous titanium with different SiC(0–7.5wt.%) content was prepared by the conventional powder metallurgy method. Results revealed that SiC significantly improves porous titanium's densification and sintering properties. Moreover, when the SiC content is 3wt.%, the compressive capacity of porous titanium reaches 191.1Mpa. Likewise, the addition of SiC significantly improves the hardness and strength.
