- 摘要:
- 对M2钢进行循环氮化时效工艺研究,以改善M2钢的耐蚀性能。结果表明,超声喷丸预处理、滚压预处理,以及二次氧化处理,均能提高循环氮化时效处理M2钢的耐蚀性,二次氧化效果最为明显。耐蚀性的提高程度与工件最终表层氧化膜的完整性和致密性正相关。The cyclic nitriding aging process was studied to improve the corrosion resistance of M2 steel. The results show that ultrasonic shot peening pretreatment, rolling pretreatment and secondary oxidation treatment can improve the corrosion resistance of M2 steel under cyclic nitriding aging treatment, and the secondary oxidation effect is the most obvious. The improvement of corrosion resistance is positively correlated with the integrity and compactness of the final surface oxidation film.
