| Abstract: |
| This paper aims to study corrosion resistance of some structural steels and stainless steels that serves in ocean atmospheric environment. Corrosion resistance of some steels in ocean atmospheric environment was evaluated via several environmental test methods for simulation of the typical ocean environment characteristics. Generally, the corrosion resistance of stainless steel with high chromium content was excellent, while the corrosion resistance of stainless steel with low chromium content was poor in ocean atmospheric environment. Structural steels are susceptible to corrosion in ocean atmospheric environment. Passivation treatment obviously improved the corrosion resistance of stainless steel. However, it was still difficult to protect stainless steel from corrosion under long-term ocean atmospheric environment. Inorganic Aluminum Coating has excellent protection performance for steels, while silver plating accelerated the corrosion of steel substrate. In addition, the corrosion problems were likely to occur on the rough surface.When serving in ocean atmospheric environment, stainless steels should be passivated to improve the corrosion resistance. Inorganic Aluminum Coating can be used to protect structural steels and stainless steel with low chromium content from corrosion by the anodic protection, it is also notable to the design of the surface roughness in the design stage. The above methods can prevent or reduce the occurrence of stainless steel corrosion. |
