Abstract：
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.
