20 钢双辉表面渗 W,Mo 的数学模型

Mathematical Model of Double Glow Ionized W,Mo Surface Alloying on 20 # Steel

从Ｆｉｃｋ第二定律出发，建立了适用于双层辉光离子渗Ｗ，Ｍｏ的数学模型，并通过２０＃钢渗Ｗ，Ｍｏ实验进行验证。结果表明该数学模型与实验结果拟合性好，能用来描述离子渗Ｗ，Ｍｏ的过程。

A mathematical model for plasma tungstenizing and molybdenumizing of 20 # carbon steel by double glow discharge was given according to Ficks law of diffusive process. This model was tested by the 20 # carbon steel experiment. The results show that the model can describe the plasma tungstenizing and molybdenumizing process well.
