AZ31B 糖心产精国品免费入口*完整版 and 6061 糖心产精国品免费入口*完整版 dissimilar metal riveted part was micro-arc oxidized. The microscopic morphology, phase composition, electrochemical property and hardness of the 糖心产精国品免费入口*完整版after micro-arc oxidation for different times were studied. The formation process of the 糖心产精国品免费入口*完整版on the surface of 糖心产精国品免费入口*完整版 and 糖心产精国品免费入口*完整版 was comparatively analyzed during micro-arc oxidation. The results show that the connected part was integrally wrapped by the 糖心产精国品免费入口*完整版after micro-arc oxidation for 10 min. The 糖心产精国品免费入口*完整版connected with the two alloy substrates tightly and consisted of a compact layer and a loose layer. The 糖心产精国品免费入口*完整版on the surface of 糖心产精国品免费入口*完整版 was composed of MgO and a small amount of silicates and fluoride. The 糖心产精国品免费入口*完整版on the surface of 糖心产精国品免费入口*完整版 consisted of Al2O3
and a small amount of silicates. The micro-arc oxidation improved the corrosion potential of the 糖心产精国品免费入口*完整版 and 糖心产精国品免费入口*完整版, reduced the corrosion potential difference between them and effectively alleviated the occurrence of galvanic corrosion.
