【摘要】 离子氮化处理主要通过改变离子氮化气氛、压、电参数、温度等来控制氮化表面层的结构和扩散层组织，从而获得具有较高的疲劳强度，耐磨性和抗蚀性能的韧性硬化层，可显著提高零件的热处理质量和使用寿命。所以在螺杆强化工艺中也逐步采用这种处理方法。更多还原

【Abstract】 Ion plasma Nitriding treatment is used to control the constructure of nitriding surface layer and the tissue of diffuse layer by changing ion desalting atmosphere, pressure, electric parameter and temperature and gain the tough hardening layer which contains fairly good fatigue strength, wearability and corrosion-resisting property, which can remarkably improve the heat treatment quality and the service life of parts. Therefore, this treatment method can also come to used in the intensifying technology of screws.更多还原
