ASTM G171-03 (2017) standard test method is used to determine the scratch hardness of materials by diamond contact pins. This method simulates the scratch of materials in actual use by applying a certain load on the surface of the material using diamond contact pins. In the test, the diamond contact pins are scratched under specified conditions to observe the depth and morphology of the scratch on the surface of the material to evaluate its scratch hardness. This method is suitable for a variety of materials, including metals, plastics, ceramics and coatings, and is widely used in surface performance evaluation and quality control of materials. Through the scratch hardness test of the material, it can provide data support for material selection and application to ensure that it has sufficient abrasion resistance and durability during use.
