A Surface Melting Treatment by High Energy Beams for Getting Amorphous Surface Layer |
Hu Chuanshun, Chen Xiaofeng
|
Abstract: |
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. |
