Abstract
The tribological performance of Al2O3/NiCr coating deposited on steel (SM45C) was investigated under lubrication. The parameters of sliding wear consist of normal load and coating thickness. Test result showed that there was no evidence of an improved bonding strength in the coating. However, the wear resistance of the Al2O3/NiCr coating was significantly greater than that of the Al2O3 coating. It was evident that the residual stress for the AI2O3 coating was higher than that of the Al2O3/NiCr coating from the scratch test failure of coating. The bond coating played an important role in decreasing the residual stress. Also, it was found that the residual stress had a notable influence on the wear mechanism.
