氮化处理及与之有关的浅层表面硬化处理工艺,可在工件变形最小的情况下提高耐磨性和抗疲劳性。近年来,这些低温热处理作为代替渗碳等工艺的节能方法,己经受到
Nitriding and its associated superficial surface hardening treatment process can improve the wear resistance and fatigue resistance with minimal deformation of the workpiece. In recent years, these low-temperature heat treatment as energy-saving methods to replace carburization and other processes have been
