Abstract Seawater environmental factors are important to corrosion rate of metals, however,because of the complecity of relationship between environmental factors,it is difficult to describe the relationship by a certain definitive function.Artificial neural network (ANN)has great capability of simulating polynary nonlinear system,and it is suitable to deal with complex data.Corrosion rate of 3C steel in differert seawater environmental factors was measured by electrochemical methods.A four - layer - BP - ANN was set up and dealt with above data. The relative error between results calculated and measured was small, which showed that ANN was suitable to apply in the field of marine corrosion.
