| Abstract: |
| To solve the problem of poor wear-resistance and adhesive bonding properties of Mg alloys,which limits their application in engineering,ceramic coating was prepared on the surface of MB15 Mg alloy by micro-arc oxidation(MAO).The composition,structure,tribological and adhesive bonding properties of the coating were studied by X-ray diffraction(XRD),Scanning Electron Microscope(SEM),ball-on-disc friction test and omnipotent mechanics function testing machine.It is found that the coating,which is uniform and porous,is composed of MgO and MgAl2O4,and the anti-wear and adhesive bonding properties are improved well. |
