摘　　要：采用正交回归设计实验方法,研究了浸渗时间和热扩散时间对45钢浸渗铝渗层厚度的影响规律,建立了渗层回归方程。结果表明,浸渗时间越长,扩散时间越长,渗层厚度越大,渗层逐渐出现了空洞和裂纹,最佳浸渗工艺参数为:浸渗2 min,扩散2 h。The influence rule of diffusion and infiltration time on the alloying layer thickness was researched by the orthogonal regressive principle, and the regression equation of the alloying layer thickness was established. The resuits show that the longer diffusion, the longer infiltration time and the higher alloying layer thickness. The layer gorws gradually poorer and crack. The optimum technical parameter are diffusion for 2 hours and hot-dop for 3 minutes.
