Abstract
The possibility of high hard protective coatings formation on aluminum alloy AK12D by micro-arc oxidation (MAO) was presented. Specific features of the structure of the modified layers on the aluminum alloy of Al-12Si-Mg-Cu-Ni were investigated. The influence on the produced coatings structure and microhardness of process parameters such as installation capacitor capacity, distance between treated surface and electrode and duration of treatment was discovered.
