| 英文摘要 | Conductive mica powder is a new type of electronic conductive functional semiconductor pigment. The conductive layers such as SnO2-Sb2O3 formed on the surface make it have excellent conductivity and can be used to prepare antistatic coatings. To solve the problem of poor conductivity and electrostatic charge accumulation of organic coatings, a multifunctional composite coating was prepared on VW75 magnesium alloy after micro-arc oxidation by doping different concentrations of modified conductive mica powder particles (MCMP) in epoxy resin. The coating's corrosion resistance, conductivity, and mold resistance were evaluated. Electrochemical tests showed that as MCMP content increased, corrosion resistance improved due to the chemical stability of MCMP. The MCMP particles formed a conductive network within the coating, providing electrical conductivity. This network also created a complex diffusion path for corrosive ions, while the MAO coating insulated the metal substrate, enhancing protection. The MCMP-doped composite coating demonstrated excellent anti-mold properties compared to the magnesium alloy. These results demonstrate the potential of this composite coating as a multifunctional surface treatment for VW75 magnesium alloy in harsh environments. |
