In this paper,the micro-arc oxidation technology were utilized to fabricated the oxidation coating in order to resolve the corrosion resistance of the Mg-Al-Y alloy. The EDTA-2Na solution was introduced into the electrolyte solution for improving the coating corrosion properties.After the micro-arc oxidation process, phase structural, surface morphology and corrosion resistance of the MAO coating of Mg-Al-Y alloy were performed by XRD, SEM and Potentiodynamic polarisation measurements. The introduce of EDTA-2Na in the electrolyte solution improve the positive potential and reduced the corrosion current, which would improve the corrosion resistance properties of the Mg-Al-Y alloy.

In this work, porous TiO2 coating was fabricated on the surface of commercially pure titanium using the micro-arc oxidation (MAO) technique, and the effect of SiC particles incorporation on the microstructure and tribological properties of MAO TiO2 coating was investigated. Results show that submicron SiC particles dispersed in the MAO electrolyte were incorporated into the TiO2 coating during the MAO process and the fabricated TiO2/SiC composite coating mainly consisted of rutile, anatase and SiC phases. The pore size and surface roughness of TiO2/SiC composite coating decreased with the increasing addition amount of SiC particles in the electrolyte. Furthermore, the incorporation of SiC particles in the TiO2 coating suppressed the initiation and propagation of micro-cracks. The tribological test of coatings against GCr15 stainless steel balls show that the incorporation of submicron SiC particles in the MAO TiO2 coating decreased the friction coefficient and wear rate.

Aluminum Alloy Surface

The adhesion and bonding performance of waterborne polyurethane (PU) coating on aluminum alloy surface was improved in this study. To achieve this objective, the effects of different sodium silicate concentrations on the aluminum alloy micro-arc oxidation (MAO) layer and the adhesion strength and corrosion resistance of MAO-PU composite coating before and after modification by MAO treatment of the 7050 aluminum alloy were studied. The experimental results showed that the modification of the MAO membrane layer by a silane coupling agent could significantly improve the adhesion strength and corrosion resistance of the composite coating. Moreover, the maximum adhesion strength was obtained when the concentration of sodium silicate was 12 g L−1.
