The Infulence of Microarc Oxidation Method Modes on the Properties of Coatings

Abstract

The experimental studies of the properties of the hardened surface layer, developed by the microarc oxidation method (MAO) on the surface of Al-Si ingots from AK12D alloy have been presented here. The effect of concentration of the electrolyte components on the properties of the MAO coating, such as microhardness, thickness, porosity have been studied. The corresponding regression equations to estimate the influence of the process parameters on the quality of the developed MAO-layer, have been set up.
