Abstract: 

The possibility of using titanium in the friction units of artificial joints has been studied. Tribological characteristics of the titanium–Chirulen friction pair have been discussed. A technique for diamond-abrasive machining, polishing, and gas-phase thermal nitridation of spherical heads of pure titanium implants for hip joint endoprostheses has been developed. It is proved the increases of titanium head hardness achieved by pre-grinding the surface layer structure after cold plastic deformation.

Keywords: Chirulen, nitridation, plastic deformation, pure titanium, tearing
