Surface quenching is the main content of surface heat treatment, and its purpose is to obtain a high-hardness surface layer and a favorable internal stress distribution to improve the wear resistance and fatigue resistance of the workpiece. From a broad perspective, surface heat treatment is divided into two categories: surface quenching and surface chemical heat treatment.
