摘要
采用恰当的试验方法对涂层／基体的结合强度进行正确评价，是表面工程技术中耐磨涂层体系研究发展中的重要工作。本文采用有限单元法对一种普遍采用的涂层剪切结合强度测定标准进行了力学计算。通过对涂层／基体交界面上的应力分布的分析表明，采用这一试验方法测定涂层剪切结合强度将会造成较大的误差。提出了一种改进的试验方法，在这种方法中对试件的形状和尺寸进行了修改。
It is of great important in the research and application of coating systems for tribological applications to evaluate coating/substrate bonding strength in a proper test procedure. Mechanical evaluations of a widely adopted coating shear bond strength test standard were conducted via the finite element method. Analyses of the stress distribution on the coating/substrate interface indicated that significant errors would be introduced if this test standard were used to determine coating shear bond strength. A new test procedure with modified specimen shape and dimension was proposed, which was then verified for effectiveness.
