氩离子轰击试验表明氩离子轰击使35CrMo钢工件表面的化合物层呈柱状晶形貌,大大提高了氮在化合物层中的扩散能力,保持了扩散层中氨的浓度梯度,从而为氮的继续渗入提供了通道。采用离子硫氮碳共渗、氩离子轰击、离子硫氮碳共渗工艺共同处理后的35CrMo钢制风冷机齿轮,有效渗层(HV>500)达0.2～0.3mm,总渗层达到0.5mm,使用寿命明显提高。
Argon ion bombardment experiments show that the argon ion bombardment makes the compound layer on the surface of 35CrMo steel have a columnar crystal morphology, greatly improving the ability of nitrogen to diffuse in the compound layer, maintaining the concentration gradient of ammonia in the diffusion layer, thereby continuing the infiltration of nitrogen Provided access. The 35CrMo steel air-cooled gear co-treated with ion-sulfurized nitrocarburizing, argon ion bombardment and ion-sulfurized nitrocarburizing process had an effective permeation zone (HV> 500) of 0.2-0.3mm and a total permeation rate of 0.5 mm, significantly improve the service life.
