A review was given on the development of micro-arc oxidation technology since its establishing in 1960s, with the power supply, electrolyte, and substrate metals to be focused on. The distribution rules of the compositions and phase structures of the micro-arc oxidation coatings, as well as the influences of current density, oxidation time, voltage, electrolytes, and other factors on the growth and properties of the coatings were summarized. It was pointed out that there still exist some disadvantages in the related theoretical research and production cost control of the micro-arc oxidation technology, though it has a promising application perspective.
