本文总结了划痕试验法的物理模型及研究现状 ,临界载荷与涂层和基体之间的界面剪切强度和附着功有物理关系 ,临界载荷能够表征涂层与基体的结合力。
This paper summarizes the physical model and research status of the scratch test method. The critical load is related to the interfacial shear strength and adhesion between the coating and the substrate. The critical load can characterize the adhesion between the coating and the substrate.
