Effect of TiN Coating on Functional Properties of Implant Titanium Alloy

Abstract:

Surface engineering is considered a very prospective method of improving functional properties of implant alloys. Many publications reported the excellent influence of TiN coating on wear resistance as well as corrosion properties of titanium alloys. However, some authors pointed the danger of delamination of thin coating during exploitation. The aim of presented work was research of effect of TiN coating obtained by the RF-PCVD method on tribological and corrosion properties of Ti6Al4V alloy. Investigations performed by the simulator of hip joint friction as well as corrosion tests carried out at various temperatures showed adverse influence of TiN coating on wear and corrosion resistance. Analysis of presented date demonstrate that results strongly depend on test conditions.
