Effect of sealing treatment on corrosion behavior of plasma sprayed ZrO2 coated Cf/Mg composites

To improve the corrosion resistance of plasma sprayed ZrO2 coated Cf/Mg composites, the pores on the ZrO2 coating were sealed with the SiO2 coating prepared by sol-gel technology. The surface porosity of the ZrO2 coating was reduced by 65.47% after the SiO2 sealing treatment. The electrochemical res...
