氮化后的零件具有较高的硬度,耐磨性,抗疲劳强度,及较高的抗蚀性,(不锈钢、耐热钢除外),并且变形小等特点。所以,成为机械工业中不可缺少的一种化学热处理工艺。但是氮化存在的主要缺点是生产周期长,一般要几十个小时,甚至上百个小时,因而中产率低,成本高。例如:我厂生产的零件“套筒”(材料15CrllMoV),氮化处理需要30～35小时,为了改革这种旧的工艺,提高生产率,降
Nitrided parts with high hardness, wear resistance, fatigue strength, and high corrosion resistance (stainless steel, heat-resistant steel except), and small deformation and so on. Therefore, it has become an indispensable chemical heat treatment process in the machinery industry. However, the main disadvantage of nitriding is the long production cycle, usually tens of hours, or even hundreds of hours, and therefore low yields and high costs. For example: I produced the parts “sleeve” (material 15CrllMoV), nitriding takes 30 to 35 hours, in order to reform this old process, increase productivity, reduce
