摘要
于1993年1－7月，在室内模拟条件下研究钢铁试样在海泥-海水跃变区的电化学腐蚀特征。发现钢试样在该跃变区产生了电偶腐蚀，电偶极性在买验期间内发生逆转，试验前后电偶试样的稳定自由腐蚀电位都发生正移，且水中试样电位正移植大于泥中试样的正移值，还发现温度对各电化学参数无明显影响。
Laboratory study of the electrochemical corrosion behaviour of steel in the jucture area between sea clay and seawater under simulated condition showed that (1)galvanic corrosion occurred between steel samples buried in sea clay and hung inseawater, (2) the polarity of the galvanic cell reversed during the test, (3) tlie stable free corrosion potential of galvanic samples moved toward the positive directionafter the test, and the movement of the free corrosion potential of samples in seawater was more than that in clay, (4) the sea temperature had no obvious relationship with the other parameters under the testing condition.
