Additives are classified by conductive agent, passivator, modifier and stabilizer. The influences and working mechanism of different varieties of additives on ceramic coatings are analyzed. Effects of electrolytes on surface appearance, properties and making technics of ceramic coatings are reviewed. The common electrolyte systems in micro-arc oxidation(MAO) for aluminum alloy are summed up. It is pointed out that preparing electrolytes reasonably and designing coatings with different function will be the study emphases of MAO in the future.
