AbolishedMetallic and related coatings--Vickers and Knoop microhardness tests
金属覆盖层及其他有关覆盖层 维氏和努氏显微硬度试验
Application Summary AI generated
This standard specifies the methods for performing Vickers and Knoop microhardness tests on metallic and related coatings. It is applied in manufacturing and quality control to measure the hardness of thin coatings, such as electroplated, anodized, or thermally sprayed layers, on components like automotive parts, electronic connectors, and industrial tools. The standard ensures consistent evaluation of coating durability and wear resistance under low-load indentation conditions.
