Titanium and some of its alloys are widely used as metallic biomaterials due to their excellent mechanical properties, corrosion resistance, and biocompatibility. In the present study, highly porous titanium foam with a porosity of 80% is produced by using a novel powder metallurgical process, which includes the adding of the selected spacers into the starting powders. The porous titanium foam is characterized by image analyses, optical microscopy and scanning electron microscopy. Mechanical properties are investigated by compressive tests. These biocompatible porous titanium foams with a porosity of 80% and pore size between 200-500 μ m are expected to be used as biomaterial candidate for bone implants because its open-cellular structure permits the ingrowths of new-bone tissues and the transport of the body fluids.
