实验研究了渗碳及碳氮共渗热处理工艺在汽车齿轮生产中的实用效果。结果表明,该工艺结合齿轮挂具技术,不仅可以实现组织易控、操作简单的目的,还可以获得一定数量的表层残余奥氏体和碳化物的混合物,提高车用齿轮的强度,得到优良的材料塑形和韧性,从而提高了车用齿轮的抗疲劳寿命;该技术应用到实际生产中,缩短制造周期,节约生产成本,提高工厂的经济效益。 The effects of carburizing and carbonitriding heat treatment on the production of automobile gears were experimentally studied. The results show that this technology combined with gear rack technology not only can achieve the purpose of easy organization and simple operation, but also can get a certain amount of mixture of residual austenite and carbide on the surface to increase the strength of the gear for vehicle, and obtain excellent Material shaping and toughness, thereby improving the anti-fatigue life of the car gear; the technology applied to the actual production, shorten the manufacturing cycle, save production costs, improve the economic efficiency of the factory.
