摘　　要：对38CrMoAlA钢大模数齿轮进行了深层离子渗氮工艺试验,检测了离子渗氮层的组织和显微硬度分布。结果表明,38CrMoAlA钢大模数齿轮经深层离子渗氮后,其耐磨性显著提高。中碳合金钢大模数齿轮深层离子渗氮工艺或许将部分代替低碳合金钢气体大模数齿轮的渗碳、淬火工艺。Experiment on deep ion nitriding of large module gear of 38CrMoA1A steel was performed. Microstructure and micro-hardness profile in the case were tested. The results show that wear resistance of the gear is improved remarkably. Perhaps, gas earburizing and hardening of low carbon alloy steel will be replaced partially by deep ion nitriding of of medium carbon alloy steel for large module gear.
