电子束表面淬火与表面合金化是通过高能量密度的能源对零件进行表面处理,是七十年代发展起来的一项新技术。与其他表面淬火和表面合金化方法相比,它具有优良的表面质量,不需要淬火介质,变形小,电热转换效率高,能大大节约能源,表面合金化时极大的缩短工艺时间等优点。 Electron beam surface hardening and surface alloying is the surface treatment of parts through high-energy-density energy, which is a new technology developed in the seventies. Compared with other surface hardening and surface alloying methods, it has excellent surface quality, does not require quenching medium, small deformation, high electrical conversion efficiency, can greatly save energy, the surface alloying greatly shorten the process time and so on.
