Abstract
Titanium foam is considered as a potential bone substitute because of its good biocompatibility. Porous titanium was prepared by powder metallurgy with titanium powder used as raw material and urea as pore-making agent. The pore characteristics and mechanical properties of porous titanium with different pressures on porous titanium were studied when the volume fraction of urea was 60%, the sintering temperature was 1100 °C, and the holding time was 1.5 h. Analysis is done by means of SEM. The results show that the porosity decreases with the increase of pressing pressure , and the porosity is the lowest when the pressing pressure is 150 MPa. Subsequently, due to internal defects, the porosity increased slightly. At the same time, the pore structure and mechanical properties are best when pressing pressure is 150 MPa, which matches the mechanical properties required by human skeleton.
