In this article, the microscopic patterns and phase constituents of ceramic coatings formed by microarc oxidation(MAO coatings) on aluminum alloy in the different treated time were analyzed, and the growth process of the coatings is studied by scanning electron microscope(SEM) and X-ray diffractometer (XRD) ; The affected factors on wear-resisting property of MAO coatings on aluminum alloy were investigated by abrasion test under the lubrication of oil.
The results show that Hard MAO ...
