摘　　要：采用正交实验的方法在不需进行重复试验的情况下,把渗铝工艺中的渗铝温度、保温时间、渗剂中铝粉含量和氯化铵含量的比值3种参数作为3个正交因素,分别进行9组试验。借助能谱仪(EDS)分析每一组试样的渗铝层厚度,以优化渗铝工艺参数。The thickness of aluminizing layer was studied by taking aluminizing temperature, time, the ratio of A1 and NH4C1 content of pack powder as aluminizing process parameters. Proper orthogonal experiment array was designed. That includes 3 orthogonal factors, 9 groups of test. The aluminizing layer thickness was analyzed by energy dispersive spectrometer （EDS） to optimize the aluminizing process parameters.
