| Abstract: |
| Objective To study on differences of corrosion resistance between surface treated with conventional hard chrome and tungsten carbide WC-10Co-4Cr for 35Cr2Ni4MoA. Methods Laboratory accelerated corrosion environment tests were carried out for two surface treatments of 35Cr2Ni4MoA Materials. The accelerated corrosion test had a total of 8 cycles. The surface corrosion of 35Cr2Ni4MoA material was described by pit depth, corrosion area, and corrosion amount per unit area. Results The corrosion resistance of surface treatment of 35Cr2Ni4MoA material with tungsten carbide WC-10Co-4Cr was better than that of traditional hard chrome plating. Conclusion The surface treatment of tungsten carbide WC-10Co-4Cr can effectively improve the surface corrosion resistance of 35Cr2Ni4MoA material under marine environment.a |
