| Abstract: | The corrosion resistance of 40Cr steel with different nitriding temperature and post oxidation treatment was compared, and the corrosion resistance of 40Cr steel under different surface protection conditions were compared through the salt spray corrosion test method. The results show that when the nitriding temperature of 40Cr steel is between 560 ℃ and 580 ℃, the neutral salt spray test time can reach more than 200 h; after the edge protection and oil seal treatment of the 40Cr steel trented by nitriding oxidation treatment, the neutral salt spray test time can reach 200 h, and the appearance rating (RA) is 10. |

| Keywords: | 40Cr steel neutral salt spray test nitriding and oxidation treatment surface states corrosion resistance |
