Abstract

Titanium foam is considered as a potential bone substitute because of its good biocompatibility. In the preparation of porous titanium, titanium and cobalt can be distributed evenly in the matrix of porous titanium alloy with cobalt as an alloy element. Such intermetallic compounds possess better mechanical properties. The compressive properties of porous titanium with different cobalt powder addition on it were studied when the volume fraction of urea was 60%, the sintering temperature was 1100 °C, and the holding time was 1.5 h. The results show that with the increase of cobalt content, the compressive properties of porous titanium–cobalt alloy is obviously improved compared with pure porous titanium. When the cobalt content is 10 wt%, the yield strength of the material reaches the maximum value of 363.76 MPa.
