Abstract: The surface treatment technology can not only maintain the original characteristics of the base material, but also give new performance of the product surface to improve the physical and mechanical properties of the product surface. This paper expounds the surface treatment methods applicable to commonly used machined parts, stamping, die-casting, forging and other metal parts produced by different processes in the field of automobile parts manufacturing, analyzes the test plan that should be selected for the parts after electroplating, shot blasting, sand blasting, shot blasting and spraying treatment, and provides reference and basis for the development and verification of automobile metal parts requiring surface treatment, so as to ensure the effect and quality of surface treatment.
