采用二次正交回归方法分析研究了工艺参数对Ni Cr Mo Nb离子多元共渗的影响 ,实验结果表明 ,渗层表面合金元素质量分数w和渗层厚度d与宏观工艺参数之间存在明确的对应关系 ,并建立了两者之间的数学模型 ,确定了工艺参数源极功率密度PS、气压 p和极间距D对渗层表面合金元素的w和d的影响
The influence of process parameters on the multicomponent NiCuMoNi infiltration was analyzed by quadratic orthogonal regression. The experimental results show that there is a clear relationship between the alloy w and the thickness of the infiltrated layer and the macroscopic technological parameters And established the mathematical model between the two to determine the process parameters source power density PS, pressure p and pole spacing D on the surface alloying elements of w and d
