上海材料研究所利用我国富有的稀土元素,开发稀土气体渗氮和稀土软氮化新工艺。经过试验研究确定了稀土催渗剂的配方及渗剂中稀土加入量的最佳范围。较深入的研究探讨了稀土对气体渗氮和软氮化的过程、渗层组织和显微硬度以及处理后材料的冲击韧性、滑动磨损,冲击磨损、弯曲疲劳等性能的影响。 Shanghai Institute of Materials using our rich rare earth elements, the development of rare earth gas nitriding and rare earth nitrocarburizing new technology. After the pilot study to determine the rare earth kaolinite formulations and penetration of the best range of rare earth addition. More in-depth study of the rare earth gas nitriding and nitrocarburizing process, the microstructure and hardness of the infiltration layer and the treated material impact toughness, sliding wear, impact wear, bending fatigue and other properties.
