| Objective To study the corrosion resistance of automobile brake discs subject to three protection technologies in tropical ocean atmosphere. Methods The contrast test was conducted by means of outdoor exposure test in Wanning test station for the brake discs subject to three protection technologies. Results Brake disc with chrome-free zinc-aluminum coating 1 got rusty seriously and suffered most severe corrosion in tropical ocean atmosphere. However, the brake discs with chrome-free zinc-aluminum coating 2 and subject to graphene protection technology were rusted slightly. Conclusion The corrosion resistance of the chrome-free zinc-aluminum coating 1 is the worst among the three kinds of protection technologies. The corrosion resistance and environmental suitability of chrome-free zinc-aluminum coating 2 and graphene protection technology are good, which can provide good corrosion protection for the substrate in tropical ocean atmosphere. |
