| 摘 要： | 按照Van-Hoff公式K_t=2~(■/10)确定人工加腐蚀系数;按照几何方程y=K_e·t~n+A和直线方程y=K_L·t+C在电子计算机上分别对土壤腐蚀和大气腐蚀的实验数据进行曲线拟合。对热浸锌层在腐蚀介质中的电化学过程的分析结果表明,上述数据处理及其结果与实际情形相符。

| Abstract: | The accelerated corrosion coefficient can be calculated from Van—Hoff's equation K_t= 2~(t_2-t_1/10). The experiment data of corrosion rates in atmospheric environments and that in soil are curve fitted by computer according to the Straight Line Equation Y = Ki·t+C and Power Law Equation Y=Ke·t~n+A. The analytical results of electrochemical process of hot-dip galvanized steel in rusting medium demonstrated that the accelerated corrosion test conforms to the practical conditions in the Salt Lake area of Qinhai Province. |
