Abstract
A process for producing sintered titanium-graphite having improved wear resistance and low frictional characteristics is described. The said process which produces titanium-graphite composites having a triphasic structure with controlled porosity and a graphite lubricating film, comprises sintering a mixture of titanium and graphite powders in which the percentage of graphite may vary from 4 to 8 percent at temperatures from about 800.degree. C. to 1600.degree. C., for about 1/2 to 2 hours, under a compaction pressure of 0.17 to 0.62 MPa. The composites have applications in biomedical engineering and other fields of engineering due to their biocompatibility, strength and improved wear resistance.
