Abstract
During microarc oxidation of the D16 alloy with intermediate treatments aimed at increasing the pH of electrolytes in through pores, it has been established that the mechanism of their effect on the ultimate thickness of the coatings is identical. These treatments increase the efficient through porosity. The power evolved in the channels of microdischarges at microarc oxidation of the alloy after such treatments becomes significantly lower than the critical value at which macrodefects are formed in the coating.
