| Abstract: | Accelerative corrosion experiments were conducted on Q235 carbon steel in seashore salt soil in order to determine acceleration ratios and dynamic correlation coefficients.The experimentation utilized constant temperature and water content,various temperatures,and different water contents to calculate mass loss of steel samples in the lab;also,samples were put in the ground one meter deep,so as to perform addition analysis in the field.The results indicated that the acceleration ratio increased when the tem... |
