THE ANALYSIS OF ATMOSPHERIC CORROSION LAW OF WEATHERING AND CARBON STEEL

Discuss the variance analysis of atmospheric corrosion at BEIJING,QINGDAO, JIANGJIN and WUHAN of weathering and carbon steel, No Significant Variance has been observed between atmospheric corrosion date of weathering and carbon steel at BEIJING.Regression analysis of atmospheric corrosion date at BEIJING shows that relationship between corrosion date of weathering and carbon steel and time follows linear bilogarithmic law. According to regression equation, the atmospheric corrosion of weathering and carbon steel at BEIJING may be predicted.
