Influence of Cobalt on the Structure and Properties of Micro-arc Oxidation Coatings on 2A12 Aluminum Alloys

  • Liqin Shen

Abstract

A blue ceramic coating was applied on 2A12 aluminium alloy by microarc oxidation (MAO) in the presence of CoSO4. The morphology, phase constituent, corrosion resistance and wear resistance of 2A12 aluminium alloy microarc oxidation coatings were characterized by various techniques. The MAO coatings were found to be smoother and denser when CoSO4 was used to the electrolyte. Also, In terms of corrosion resistance and wear resistance, the microarc oxidation coating prepared by CoSO4 is superior to that without CoSO4.
