摘要:
粉末渗锌过程是一种固态扩散反应,具有扩散速度慢、冶金反应时间较长的局限性,为此通过改变渗剂的尺寸将其升级到纳米量级,研究了使用纳米锌粉及稀土后对传统粉末渗锌工艺的影响。试验表明:采用纳米锌粉及稀土组成的渗剂对渗锌过程及渗层性能有较大改善作用,其结果为研制开发一种新型低能耗、高效率的粉末渗锌工艺提供了基础。

Abstract:
The sherardizing is a solid state diffusing process with the limitation of lower diffusing speed and longer alloying reaction time. The influences of nano zinc powder and rare earth in the sherardizing materials on the conventional sherardizing technology were investigated through changing the size of ingredient to the degree of nano magnitude in this paper. It was shown that the sherardizing materials using nano zinc powder and rare earth were more beneficial to improve the sherardizing process and the performance of surface alloying layer. These results provided the foundation to develop a relatively new sherardizing technology with lower consumed energy and higher efficiency.
Key words:  nanometer  sherardizing  surface alloying
