A case of uniform corrosion is the corrosion of reinforcing steel in concrete. Steel is placed in concrete to reinforce it as concrete is a brittle material in tension, so the steel reinforces it. If the Pourbaix diagram for iron is examined, Chapter 2, then the conditions of concrete a high pH, are such that a passive film should be present ...
