摘要：

The critical load for adhesion of 75% WC-Co + 25% Ni alloy plasma sprayed coatings was evaluated by an interfacial indentation test. A statistical analysis-piecewise linear regression-was used to estimate the critical load Pc and its confidence interval. It was determined that a post heat treatment increases the practical adhesion load of plasma sprayed coatings. This increase was attributed to interdiffusion mechanisms verified at the interface between the coating and substrate.
