Enhanced corrosion protection of AZ31B magnesium alloy by MgAl-LDHs composite coatings double-doped with imidazolium ionic liquid and sodium dodecylbenzenesulphonate
Abstract:Herein, we prepare two types of MgAl-LDHs coatings single-doped by imidazolium ionic liquid 1decyl-3-methylimidazolium bromide ([Demim]Br) or sodium dodecylbenzenesulphonate (SDBS) and double-doped by [Demim]Br and SDBS on AZ31B Mg alloy by using an in-situ hydrothermal treatment. Their surface morphology and corrosion resistance immersed in 3.5 wt-% NaCl solution are explored. Our results suggest that the double doping of [Demim]Br and SDBS will change the surface morphology of the coating and a uniform and d… Show more
