    Corrosion Management: Atmospheric Corrosion Prediction of Carbon Steel

    Published: August 01, 2018
    Author(s): C.M. Lo, Department of Environmental Engineering, National Chung Hsing University, Taiwan, Republic of China; and Harbor & Marine Technology Center, Institute of Transportation, Ministry of Transportation and Communications, Taiwan, Republic of China L.H. Tsai, Harbor & Marine Technology Center, Institute of Transportation, Ministry of Transportation and Communications, Taiwan, Republic of China H.H. Lai and W.T. Wu, Department of Materials Science and Engineering, National Chung Hsing University, Taiwan, Republic of China M.D. Lin, Department of Environmental Engineering, National Chung Hsing University, Taiwan, Republic of China

    The main objective of this study was to develop a forecasting model of carbon steel corrosion rates in atmospheric exposures. The corrosion rates in the industrial and coastal zones were all higher than the corrosion rates in the rural zone. The corrosion rates...
