海洋用钢在海底泥土区常承受具大的应力 ,而应力将对海洋用钢的腐蚀破坏行为产生影响 .本文选用一种常用的海洋用钢 ,采集含有硫酸盐还原菌 (SRB)的天然海泥 ,研究试样在海泥中的腐蚀行为 ,以及试样在有裂纹和无裂纹存在时的电流响应特征

The corrosion failure behavior of marine steel is affected by stress,which exists in offshore structures at sea_mud region.In order to conduct the study of stress on the electrochemical response of a selected steel,a kind of natural sea_mud containing sulfate reducing bacteria(SRB) was collected.The electrochemical response of cyclic stress of the specimen with and without cracks in sea_mud was analyzed.
