Influence of La2O3 addition on nano indentation hardness and residual stress of Stellite 6 coating prepared by plasma cladding

In order to distribute the residual stress in the plasma cladding Stellite 6 coating, the La2O3 was added. The results show that the 0.8 wt% La2O3/Stellite 6 coating has the smallest grain size, the maximum nano indentation hardness and the minimum value of residual stress.229
