COMPARISON OF SURFACE PROPERTIES OF Ti-6Al-4V COATED WITH TITANIUM NITRIDE, TiN+TiC+Ti(C,N)/DLC, TiN/DLC AND TiC/DLC FILMS BY PLASMA-BASED ION IMPLANTATION
COMPARISON OF SURFACE PROPERTIES OF Ti-6Al-4V COATED WITH TITANIUM NITRIDE, TiN TiC Ti(C,N)/DLC, TiN/DLC AND TiC/DLC FILMS BY PLASMA-BASED ION IMPLANTATION

1. IlltroductionThe high yield strength and toughness, moderate modules, low density, good corrosionresistance and exceptional biocompatibility of Ti-6Al--4V alloy have made it increasinglypopular in industrial and medical application. But the alloy does not have enough wearresistance, and so is restricted in surface, particularly tribological applications to a certain e.tent1--2]. It has been demonstrated that plasma-based ion implalltation (PBll), anew cost-effective technique for improvi…
