本文通过对工业纯铁、20钢、45钢、T8钢进行双层辉光离子W、Mo共渗,探讨了钢中含碳量的影响。结果表明,钢中或试件表面实际含碳量不同时,可形成不同的渗层组织。W、Mo元素渗入钢中将引起碳向渗层迁移,形成贫碳区。在W、Mo的渗入和表面阴极溅射共同作用下,试件表层产生脱碳现象,试件电压愈高,电流密度愈大,脱碳层愈深。
In this paper, double-layer glow-ion W and Mo infiltration of industrial pure iron, 20 steel, 45 steel and T8 steel were carried out to discuss the influence of carbon content in steel. The results show that when the actual carbon content in the steel or on the specimen surface is different, different infiltrated layers can be formed. W, Mo element infiltration into the steel will cause migration of carbon to the infiltration layer, the formation of lean carbon area. Under W and Mo infiltration and surface sputtering, decarburization occurs on the surface of the test piece. The higher the voltage of the test piece, the larger the current density and the deeper the decarburized layer.
