Abstract

A novel β Ti-25wt%Nb-7wt%Zr-10wt%Mo-calcium pyrophosphate (CPP) composite that is a biocompatible alloy without elemental Al or V was fabricated by spark plasma sintering (SPS) at 1000°C under 60 MPa using high energy mechanical milled (HEMM) powder. The effects of CPP contents and milling time on biocompatibility and mechanical property have been investigated. By X-ray diffraction (XRD), chemical reaction during the sintering was occurred and revealed new phases, Ti2O, CaO, CaTiO3 and Ti xPy. Vickers hardness of composites increased with increase milling time and addition of CPP contents. The biocompatibility of the Ti-Nb-Zr-Mo alloys was improved by addition of CPP.
