Which outcome accelerates the corrosion rate of stainless steel in seawater environments?

💡 Explanation

When stainless steel is galvanically coupled to a less noble metal in seawater, an electrochemical cell forms because the less noble metal corrodes preferentially, accelerating the corrosion rate of the stainless steel. Therefore corrosion accelerates, rather than passivating or slowing when oxygen or water salinity is changed.
