随着工业的发展,氮化处理越来越广泛地用于各种高精度、高速度、耐磨、耐疲劳等零件,如高速大功率内燃机曲轴、汽缸套、高精度磨床主轴、座标镗床主轴、水压机阀门、航空内燃机零件等的制造中。目前一些问题,如零件在氮化时的放磨余量对质量的影响,氮化 With the development of industry, nitriding is more and more widely used in various parts with high precision, high speed, wear resistance and fatigue resistance, such as high speed high power internal combustion engine crankshaft, cylinder liner, high precision grinding spindle, jig boring machine Spindle, hydraulic valve, aviation engine parts and other manufacturing. At present, some problems, such as parts in the nitriding put the rest of the quality of the impact, nitriding
