Corrosion Control through a Better Understanding of the Metallic Substrate/Organic Coating/Interface.

Abstract

Corrosion potential measurements, polarization resistance studies and cathodic delamination studies provide evidence that steel abrasively blasted with alumina exhibits a lower initial rate of corrosion in mild media than similar steels blasted with steel grit or abraded with silicon carbide paper. Auger spectroscopy and electron microprobe analysis revealed the presence of significant aluminum on the surface, largely in the form of embedded particles but possibly also as a constituent of the oxide film. Nonmetallic abrasive blasting may have application in the chemical modification of metal surfaces.
