Abstract

A facile anodic treatment for magnesium alloy was proposed in a choline chloride-ethylene glycol based deep eutectic solvent (DES). Conversion films with interconnected porous networks and jagged nanorod arrays can be formed, which depends on the applied anodic current density. Crystallographic orientation of the substrate is accordingly changed. The conversion films are mainly composed of MgCO₃ which results from the interaction between the Mg alloy and the released species from the decomposition of DES. A higher anodic current density produces a better corrosion resistant conversion film. Superhydrophobic and slippery surfaces can be achieved on the as-prepared conversion films to further improve the corrosion resistance.
