R & D of the Reactive Paint Coating for Corrosion Protection by Controlling Rust on Steel

Abstract

The reactive paint which can control rust structure during corrosion process is introduced with discussing the structure and anti-corrosion properties of rust layer formed on a mild steel. It was shown that the reactive paint leads to preferential formation of α-FeOOH structure in the rust layer. The change in rust structure results in suppression of cathodic reaction and prevents corrosives from passing through the rust layer. The reactive paint can be employed for rusted steels as well as for steels with clean surface.
