摘要：

To measure the interfacial toughness of strong Cr-plating coating on substrate, experiment of laser periodical scanning into the surface of Cr-plating coating on steel substrate is carried out using CO2 continuous laser. It is observed that this mode of heating can induce chromium coating to periodically buckle along the laser scanning direction. Based on this observation, incorporating the theory of coating buckling deformation, the laser buckling method is presented. This method can be used to measure the interfacial toughness of Cr-plating coating with the help of just one buckling unit. As a case study, the interfacial toughness of the chromium coating on steel substrate is measured by this method.
