英文摘要：

The optimal thickness of the surface coating for laser shock processing was studied. The interaction mechanism between laser and coating, and its relation among coating properties were investigated;the gasification velocity and optimum thickness of the coating were obtained;the influence factors on thickness of the coating were analyzed and modified ; which provided a theory reference to correct quote the computational formula about the thickness optimizing of coating for the laser shock processing.
