| Abstract: | The chemical methods for treating magnesium alloy surface include chromate conversion,phosphate,fluorozirconate,stannate,rare earth conversions and so on.The treated conversion coatings have pores and micro-cracks,so a sealing treatment is needed.The conversion coating of magnesium alloy which has a certain porosity can be improved by sol.Through heat treatment or MAO of the coated chemical conversion film,the binding strength between sol and the film as well as the corrosion resistance of the film can be i... |
