Analysis and Forcasting for Main Factors of Corrosion to Metals in Ocean Enviroment

The relationships between ocean corrosion of metal and the ocean environment were studied by grey relational analysis methods. Under the submergence, the main factors of corrosion for A₃ steel in ocean environment were found in accordance with grey relation grade. Neural network was applied to set a madel of ocean corrosion to A₃ steel. Then the model is used to predict the corrosion rate of A₃ steel in the new ocean environment and a satisfied result is obtained.
