Wear behavior of Diamond-like Carbon Deposited on Ti6Al4V Prepared with Surface Mechanical Attrition Treatment

Abstract : Surface modification by deposition of hard coatings is a way to overpass the poor wear resistance of some metallic materials and one potential material is the Diamond-Like Carbon (DLC). We investigated the wear behavior, and the adhesion of the DLC deposited on a Ti6Al4V (Ti64) alloy after Surface Mechanical Attrition Treatment (SMAT). The SMAT was applied using 100Cr6 steel balls, and the DLC was deposited through the sputtering method. The nano-hardness was evaluated using a MTS Nano Indenter XP. The adhesion of the DLC was evaluated using a CSM Revetest, and the wear tests was performed in a reciprocating linear tribometer from CSM Instruments. The mean wear rate for the Ti64 was 437x10-6 mm3/N/m against 5x10-6 mm3/N/m for the Ti64+SMAT+DLC. The SMAT reduced the wear rate of the DLC coating, showing that the SMAT might be a viable treatment with promising results regarding the DLC wear resistance.
