获得表面非晶层的高能束熔凝处理方法

A Surface Melting Treatment by High Energy Beams for Getting Amorphous Surface Layer

综述了现代激光束和电子束表面快速熔凝处理的有关理论；对比了激光和电子束与材料表面热作用的差异及熔换层试样制备的几种方法的优劣：论述了功率密度、扫描速度和光束处理方式对表面快速熔凝处理的影响。

This paper introduced the related theories of rapid melting treatment by modern laser and electron beams. Their diffeence in thermal effects on the surface of materials, and the advantages and disadvantages of several preparation methods of melting layers were compared. The effects of power density, traverse speed and mode of beams on the melting treatment were also describing.
