涂层/基体材料界面结合强度测量方法的现状与展望

界面结合强度是涂层/基体材料体系中的一项重要力学性能指标.而表征与评价涂层/基体材料的界面结合强度又得依靠实验方法的测定.由于涂层/基体材料体系的多样性与复杂性, 至今还没有形成适合于测量这类材料的界面结合强度的标准方法.目前, 常用来测量涂层/基体材料的界面结合强度的方法有：拉伸法、剪切法、弯曲法、划痕法、压入法等.本文就目前表征与评价涂层/基体材料界面结合强度的测量方法做了综述, 讨论了它们的适用范围, 比较了它们的优势与不足.

A review on measurement methods for interfacial bonding strength between coating and substrate

The interfacial bonding strength is a crucial factor in determining ultimate mechanical properties and performances of coatings and thin films, and the life of a specimen or workpiece, apart from the external factors, such as loading conditions. So the evaluation of the interfacial bond strength for a coating is an important task. However, it is difficult due to the variety of coating/substrate systems. As a result, a test that works with one film system may not necessarily work with another. In this paper, the measurement methods for interfacial bonding strength between a coating and a substrate are reviewed. The tensile test, shear test, bending test, scratch test, indentation test and dynamic test are discussed, and comparisons are made.
