Abstract

Corrosion experiments of A₃, 16Mn, 20^# as well as ZCE36-225 steel were carriedout in southern Bohai sea and Qingdao sea areas. The sea-bottom mud in southern Bohai sea areais 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 carriedout. The experiment results showed that: 1) The corrosion rate of steel in sea-bottom mud has astrong relation with mud types. The corrosion rates of steels in pure beach sand are much higherthan those in sandy mud. 2) The corrosion rates of nonelectric connected mode are hingher thanthose of electric connected modes.
