气体软氮化与渗碳淬火相比较,由于它不需要高温加热和快速冷却,所以变形小。因此,气体软氮化在齿轮上的应用目前正在研究。可是气体软氮化应用于普通的钢,由于渗层深度浅,只能限于应用在Hertz压力低于100kg/mm~2的齿轮。作者成功地研究了一种钢(RDK401),这种钢用气体软氮化方法可得到有效渗层深度(Hv513)超过0.3mm。用RDK401钢和最佳的气体软氮化工艺相结合,确保了齿轮在Hertz压力超过180kg/mm~2下服役。
Gas nitrocarburizing and carburizing compared to quenching, because it does not require high-temperature heating and rapid cooling, so the deformation is small. Therefore, the application of gas nitrocarburizing on gears is currently under study. However, gas nitrocarburizing applied to ordinary steel, due to the shallow depth of the infiltration layer can only be applied to the Hertz pressure less than 100kg / mm ~ 2 gear. The authors have successfully studied a steel (RDK401) that achieves an effective depth of infiltration (Hv513) in excess of 0.3 mm with gas nitrocarburizing. The combination of RDK401 steel with the best gas nitrocarburizing process ensures that the gears are serviced at Hertz pressures over 180 kg / mm ~ 2.
