| Abstract: | In the present study, mesoporous silica nanocontainer powders with and without inhibitor (fluoride) were dispersed in the Alkyd coatings to improve corrosion resistance of Mg metal. Then, the corrosion behavior of these coatings was studied in comparison with Mg in 2 g dm?3 NaCl solution. Electrochemical tests showed that these coatings could protect the surface from chloride attack. Moreover, release of fluoride from mesoporous silica nanocontainers leads to the formation of MgF2 as an inhibitive compound at the interface. |
