Coatings have been applied widely in aerospace, biomedical, electronic, and many other industries. The performance of a coating is dictated by the adhesion between the coating and the underlying substrate. Thus, the evaluation of coating adhesion is critical for the assessment of the quality of a coating and its fitness for service. However, this evaluation is not straightforward, and various mechanical and non-mechanical evaluation methods have been developed. This paper presents a comprehensive review of the currently most widely employed mechanical methods. The interface fracture mechanics that provides the fundamental knowledge for conducting adhesion assessment and analysis is briefly introduced. Detailed discussions are presented on various sandwich specimen-based and bimaterial specimen-based testing methods, with emphasis on the principles, merits, limitations, typical applications, and recent improvements of each method.

Acta Mechanica

自 1965 年以来，国际期刊 ACTA MECHANICA 一直是理论和应用力学领域的领先期刊之一。除了弹性、塑性、振动、刚体动力学、流体动力学和气体动力学等经典领域外，还特别关注非牛顿流体动力学、微/纳米力学、智能材料和结构等最近发展的领域，以及力学和材料界面的问题。该杂志还发表流变学、热力学以及与流体和固体的电磁相互作用等相关领域的论文。此外，也欢迎处理重大力学问题的应用数学文章。

Since its inception in 1965, the international journal Acta Mechanica has been one of the leading journals in the field of theoretical and applied mechanics. In addition to classical areas such as elasticity, plasticity, vibrations, rigid body dynamics, fluid dynamics, and gas dynamics, it places particular emphasis on emerging fields like non-Newtonian fluid dynamics, micro/nano mechanics, smart materials, and structures, as well as issues related to the mechanics and interfaces of materials. The journal also welcomes papers in related areas such as rheology, thermodynamics, and the electromagnetic interactions between fluids and solids. Furthermore, articles addressing significant problems in mechanics through applied mathematics are also encouraged.
