Abstract

The possibility of using titanium in the friction of artificial joints is studying. Tribological characteristics of the friction pair titanium-hirulen is researching. The technology of diamond-abrasive machining, polishing and gas thermal nitridation spherical heads of pure titanium implants for hip person are developed. It is proved the increases of titanium head hardness achieved by pre-grinding the surface layer structure after cold plastic deformation.
