| 摘 要： | 纯铁表面采用高能喷丸机械研磨处理,并在样品罐中添加镍粉,经过100 min的处理,镍粉均匀镶嵌在纯铁基体,并形成约100 μm铁镍合金层,经600℃热处理后,合金化程度进一步增强.界面微观研究表明,表面机械研磨时存在显著的原子扩散,可以在金属表面获得一定厚度的合金层,适当的热处理会进一步增强合金化程度,是一种新的金属表面合金化方法.

| Abstract: | Nickel powders were added to the sample container during the surface mechanical attrition treatment (SMAT) for a pure iron plate. After 100min, Ni powders were welded into the surface of iron plates to form a homogeneous layer of Fe-Ni alloy with 100 μm depth on the surface of Fe base after SMAT. The degree of alloying was further enhanced after heat treatment at 600℃. Studies on the interface microstructure indicate that there was significant atomic diffusion and formation of an alloying layer during SMAT process. And the degree of alloying was enhanced after proper heat treatment process. A new method of surface alloying of metals was thus developed. |
