Factors influencing cross-sectional indentation to evaluate coating adhesion were investigated by numerical simulation and experiments. For the model of chromium-plated steel substrate, indenter geormetry, indentation location and coating thickness were considered. The results show that the coating detaches from the substrate with the shape of fan, its size increases with intereasing the indentation distance and agrees well with computation. Generally, the tip angle of a conical indenter and the ratio of indentation distance to coating thickness are recommended to be 90 and 2 to 3, respectively.
