Abstract
Abstract
The article presents the results of the coatings erosion resistance experimental studies obtained by microarc oxidation using the AK4-1 aluminum alloy. The coatings formation modes by MAO varied in relation to the electrolytic components KOH, Na2SiO3 (gr/lconcentration); current density j (A/dm2) and the cathode/anode (Ic/Ia) currents ratio. The MAO coatings erosion resistance was determined from the ablation rate while the sample was blown with Al2O3 powder.
