Abstract

Corrosion experiments of A 3, 16Mn, 20 # as well as ZCE36_225 steel were carried out in southern Bohai sea and Qingdao sea areas. The sea_bottom mud in southern Bohai sea area is the sandy mud and that in Qingdao sea area is pure beach sand. In this experiment, the compareing test of two modes with electric connected and non_electric connected modes was carried out. The experiment results showed that: 1) the corrosion rate of steel in sea_bottom mud has a strong relation with mud types. The corrosion rates of steels in pure beach sand are much higher than those in sandy mud. 2) The corrosion rates of non_electric connected mode are hingher than those of electric connected modes.
