Wear Properties of Biocompatible Ti Implant due to Nitrogen Ion Implantation

질소이온주입에 따른 생체안전성 티타늄 임플란트의 마모특성

In this study, plasma source ion implantation was used to improve the wear properties of biocompatible titanium implant. In order to observe the effect of ion energy and dose on wear property of titanium implant, pin-on-disk type wear tests in Hank's solution were carried out. The friction coefficient of ion implanted specimens were increased from 0.47 to 0.65 under high energy and ion dose conditions. As increasing ion energy and ion dose, the amount of wear was reduced.
