1. A super-hydrophobic manganese dioxide coating on a surface of a metallic material, comprising:
manganese dioxide microspheres; and
a stearic acid shell;
wherein the manganese dioxide microspheres are encased in the stearic acid shell;
the manganese dioxide microspheres are stacked hierarchically on the metallic material surface; and
nanosized cavities and islands are formed on the manganese dioxide microspheres.
