Effect of electrical parameters on the efficiency of the process of microarc oxidation of D69 aluminium alloy

Abstract

Results of investigations of the effect of energy parameters on the process of micro-oxidation and the quality of produced oxidised coatings on the D16 aluminium alloy are presented. The coatings formed in oxidation in different working conditions of the power source with the capacitance regulation of power are compared. The microstructure of the surface of the specimens with the coatings produced in microarc oxidation in three sets of conditions is shown.
