The Structure of Plasma-Electrolytic Coating Formed on Al–Si alloys by the Micro-Arc Oxidation Method

Аннотация

The results of a study of the structure of hardened surface layers formed by the micro-arc oxidation method (MAO) on Al-Si alloys are presented. The influence of the concentration of electrolyte components on the formation mechanism of MAO layers and the properties of the formed surfaces, such as the microhardness, thickness, porosity, and elemental composition of the surface, is shown.
