Abstract
Research on long-term corrosion mechanism of carbon steel and low alloy steel, with the Fick diffusion law, the mathematical model of atmospheric corrosion of carbon steel and low alloy steel is presented. The model is proved by using corrosion data of carbon steel and low alloy steel exposed 1,2,4,8 and 16 years in natural environment, and putting forward the complex model of three stages of corrosion of carbon steel and low alloy steel, and forecasting the corrosion law of three stages respectively. The first stage exhibits the linear function; the second stage exhibits the parabola function, the result of regression indicates that parabola function is more accurate than power function; the third stage exhibits the linear function as well.
