The Use of Titanium in the Friction of Artificial Joints

Section: Celebrating the 10th Anniversary of the Journal
Language: Ukrainian
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.
Keywords: pure titanium, formation of seizure, plastic deformation, hirulen, nitriding.
