双层辉光离子渗Inconel 625合金的工艺特性

Technological Characteristics of Double Glow Plasma Surface Alloying Ni-Base Alloy Inconel 625

摘要: 研究了在试样材料为20钢工业纯铁和18.8不锈钢上双层辉光离子渗Inconel625合金过程的工艺特性及主要的宏观参数对渗层成分的影响规律.结果表明,渗层中合金元素的总含量及其渗层合金中主要合金元素的单独含量可以通过宏观工艺参数调整而得到控制.

Abstract: The Technological characteristics and effects of technological parameters on the composition of surface alloyed layer on the matrix (20^# steel, pure iron, 18-8 stainless steel) in process of double glow plasma surface alloying Inconel 626 has been studied. The results show that changing technological parameters can control the total content of alloyed element and Ni, Cr, Mo, Nb content in surface layer.
