| Abstract: | Objective To verify corrosion resistance of 35Cr2Ni4MoA material which takes hard chrome plating and sealing surface protection. Methods Laboratory accelerated corrosion test of 35Cr2Ni4MoA material which takes surface hard chrome plating was carried out in the presence of sealing protection to study behavior characteristics of surface corrosion. The accelerated corrosion test had 8 cycles. The surface corrosion of 35Cr2Ni4MoA material was described by the depth of corrosion pits, the area of corrosion, the number of corrosion per unit area. Results The corrosion degree of test piece was obviously reduced after hard chrome plating and sealing protection of 35Cr2Ni4MoA material. Conclusion The surface treatment of hard chrome plating and sealing surface protection can effectively improve the surface corrosion resistance of 35Cr2Ni4MoA material under marine environment. |
