摘要: 通过对渗氮零件氧化处理前后的尺寸精度、粗糙度、强度进行检测,研究渗氮后氧化处理在实际生产中的适用性。结果表明,渗氮后氧化处理对零件尺寸精度及粗糙度影响很小,但对强度的影响较大,因此该工艺不适用于处理回火温度低于渗氮后氧化处理温度的调质态工件及标准紧固件。

关键词: 渗氮后氧化, 尺寸精度, 粗糙度, 强度, 紧固件强度

Abstract: By testing the dimensional accuracy, roughness and strength of nitrided parts before and after oxidation treatment, the applicability of oxidation treatment after nitriding in actual production was investigated. The results show that the influence of the process on the dimensional accuracy and roughness of parts is small, but the influence on the strength is large. Therefore, the oxidation treatment after nitriding is not suitable for the quenched and tempered workpieces and standard fasteners whose tempering temperature is lower than the oxidation temperature.

Key words: nitriding and post-oxidating, dimensional accuracy, roughness, strength, fastener strength
