The Investigation of the Effect of Micro-Arc Oxidation Modes on the Adhesion Strength of Coatings

Abstract

The paper presents the results of studies of the properties of hardened surface layers formed by micro-arc oxidation on the workpiece surfaces of aluminum alloy Al-12Si-Mg-Cu-Ni. The authors attempted to determine the influence of micro-arc oxidation modes on the properties of the modified layers. Investigation of the adhesion strength of the surface layers formed at different concentrations of electrolyte components and analysis of the change in coatings adhesion characteristics after thermal cycling were presented.
