The corrosion resistance characteristics of three coatings on magnesium alloy AZ31-conventional paint with phosphate film, cathodic electrodeposition coating (E-coating), and E-coating pretreated with silane (Mg/silane/E-coating)-have been studied by means of electrochemical impedance spectroscopy (EIS) in a 3.5 wt% NaCl neutral aqueous solution and salt spray test using ASTM B117. Silane film was obtained by dipping AZ31 specimens in diluted hydroalcoholic silanic solutions and successively curing. It was found that the corrosion resistance of the Mg alloy with E-coating was superior to conventional paint and could be further enhanced with silane pretreatment as an interfacial film. The results of water volume fraction (U saturation ) and diffusion coefficient (D) also indicated that the Mg/silane/E-coating possessed excellent compactness and corrosion resistance. A model of the corrosion mechanism for Mg/silane/E-coating has been presented through EIS analysis.

“…However, because of the low wear resistance and high chemical reactivity of Mg alloys, surface treatment is normally required for Mg alloy in order to improve their surface durability. Different surface modification techniques have been developed and used to improve the corrosion resistance of magnesium alloy, such as chemical conversion [4], plating [5], micro-arc oxidation [6]and chemical vapour deposition [7]. However, due to the high chemical activity of magnesium in aqueous solutions, most of the existed surface modification techniques fail to offer sufficient protection for magnesium alloy components in their service environments.…”

Abstract. Al coating is formed on AZ31 magnesium alloy by Cold spraying. plane and cross-sectional microstructure of cold spraying Al coating are investigated. The results show that Al particles are deformed significantly compared with original particles and Al coating is well bonded with the substrate. The microhardness of Al coating is about 178.3 HV0.1 and the bonding strength is about 27.0MPa.
