Surface morphology characteristics and improvements on corrosion resistance in anodized Mg-Al alloys as a result of sealing treatments
The effects of sealing solutions on the corrosion resistance of anodized Mg-Al alloys were investigated. As the proportion of Mg(OH)(2) increases with the increase in the NaOH concentration, the corrosion potential improves. The sealing effects were further improved by increasing the temperature of distilled water, the pH of solutions, and the proportion of Mg(OH)(2) present in the anodic film.
