AbstractThe use of stainless steel in high corrosion-risk areas represents a viable option for reducing the life-cycle cost and extending the service life of concrete structures. However, the possible galvanic corrosion between it and carbon steel continues to be a concern. In this paper the galvanic coupling behaviours of carbon steel and three different stainless steels were investigated in simulated pore solutions and concrete specimens. The results showed that the oxygen reduction reaction was much lower on stainless steel than on passive carbon steel, leading to a lower galvanic coupling current between stainless steel and corroding carbon steel than that between passive and corroding carbon steels. However, rust contamination of stainless steel was found to increase galvanic coupling corrosion on carbon steel.
