Production research on micro-arc oxidation of magnesium alloy electrombile hub

摘要

The film forming mechanism of the ceramic layer on large area magnesium alloy electrombile hub in the silicate electrolyte and the influence of micro-arc oxidation process parameters on the membrane layer quality were studied by means of SEM. The corrosion resistance of the membrane layer was detected. The production practice shows that the compact and hard ceramic layer can be obtained on the surface of magnesium alloy electrombile hub by adopting reasonable micro-arc oxidation process parameters, which has a key role in the corrosion protection of magnesium alloy surface.
