Micro arc oxidation (МAО) is one of the advanced methods of obtaining thin-layer oxide ceramic coatings on the elements of machines of different functionality, allowing considerably increasing their life. The work is devoted to investigation of wear resistance and microhardness of coatings formed by micro arc oxidation on aluminium alloys in different electrolyte types. МAО is recommended for application at different engineering and maintenance technical enterprises, that produce, restore and harden elements.
