Abstract
The work aims to summarize the research progress of coating damage detection and evaluation in recent years.Firstly,the classification of multifunctional composite coatings and their advantages and disadvantages were briefly intro-duced,and the types and mechanisms of metal coating damage were described.Then,several coating damage detection methods were introduced in detail,including three kinds of lossy detection techniques,such as adhesion test,scanning electron micro-scope observation method,and metallographic method.Five non-destructive testing techniques,such as ultrasonic testing,near-infrared thermography testing,eddy current testing,laser shear imaging,microwave testing,which were used to measure the damage of the metal coatings,were described in the perspectives of the basic principle,the application of the process,and the degree of harm to the material.In addition,damage evaluation indexes and related theoretical models were introduced.Fi-nally,the future development trend of metal coating damage detection and evaluation technology was outlooked.
