The formation of thin oxide films on piston aluminum alloys through the method of micro-arc oxidation is considered. The mechanism of the formation crystal inclusions and high-temperature structures depending on ion current density in time is described. One of the methods of surface strengthening piston aluminum alloys – micro-arc oxidation is described and analyzed. The mechanisms of oxide layers formation taking into account the impact of alloy elements of piston aluminum alloys are considered. The analysis of porous cells is carried out, basic properties of coatings are investigated.
