Effect of Microarc Oxidation Coating on the Corrosion Resistance of a Nanostructured Eutectic Aluminum Alloy
摘要
Abstract
The effect of the structure and corrosion-protective properties of the coatings formed by microarc oxidation (MAO) on a eutectic aluminum alloy with an ultrafine-grained (UFG) structure or an initial structure is studied. The UFG structure is found to increase the corrosion rate of samples by 15.3 times. The coating increases the corrosion rate of the coarse-grained alloy by 2.5 times and does not affect the corrosion rate of the sample with an UFG structure.
