GB/T 43602-2023 Focused physical vapor deposition (VD) multilayer hard coatings evaluation. It standardizes the analysis method of coating composition, covering the determination of element types and content. For the coating structure, the observation and description methods of crystal structure and interlayer interface are clarified. In terms of performance, the testing methods for key indicators such as Hardness, binding force and abrasion resistance are specified. According to this standard, the composition, structure and performance of coatings can be comprehensively and accurately evaluated, providing a scientific basis for coating mass control, optimization process and rational application in cutting tools, molds and other fields.
