The corrosion of zinc-stainless steel couples in flowing sea water

The effect of sea water flow on passivated stainless steel 304 coupled to high purity zinc was studied for more than 1000 hours at 23°C. The corrosion of both members of the couple increased over that of the metals alone. Zinc suffered severe pitting while the Stainless Steel was not visibly corroded, When the metals were exposed alone, zinc corroded uniformly while the stainless steel was not affected at all. The use of zinc coupled to Stainless Steel is not recommended in systems exposed to sea water
