A myristate coating containing Ca and Ce (Ca/Ce coating) was fabricated on the surface of an anodized magnesium alloyby a handy, rapid and facile electrodeposition method. The deposited coatings presented superhydrophobicity and excellentcorrosion properties in 3.5 wt% NaCl solution. The effects of the concentration ratio of Ca2+and Ce3+in the electrolytesolution on the morphology, hydrophobicity and corrosion properties of the Ca/Ce coatings had been studied. The formationmechanism of the Ca/Ce coatings had been discussed in detail. The results indicated that the introduction of Ce ions in theelectrolyte solution could enhance the coatings’ thickness and hydrophobicity compared with the single Ca coating. In orderto provide durable and stable protection for magnesium alloy, an appropriate ratio of Ca2+and Ce3+is requisite for the Ca/Ce coating with rare cracks and high superhydrophobicity.
