Study of the governing law of micro-arc oxidation and filling of MAO-coatings on aluminum alloys with the use of proton NBS spectrometry

摘要

The current yield for the microarc oxidation (MAO) was studied at the different current modes and different electrolytes. It was established that the current yield is 24 and 13 percent for MAO-processes at the anode-cathode mode in silicate-alkaline and phosphorus-aluminate electrolytes, accordingly. The efficiency of MAO-coating filling was observed to be depended on electrolyte chemical composition to a greater extent than on a current mode.
