Abstract
Mg(OH)2 films were electrodeposited on the surface of AZ91D magnesium alloys in Mg (NO3)2 solutions at room temperature using cathodic potentiostatic and potentiostatic-pulse methods respectively. The characteristics of the Mg(OH)2 films were investigated by scanning electronic microscope (SEM) and X-ray diffraction (XRD). The corrosion resistance of the films was evaluated using potentiodynamic polarization tests. The results show that the Mg(OH)2 films are uniform and compact without obvious defects. Mg(OH)2 films enhanced the corrosion resistance of the AZ91D alloy. The Mg(OH)2 film deposited by potentiostatic pulse method was superior to that deposited by potentiostatic method in terms of uniformity and compactness and corrosion resistance.
