Abstract
A hydrophobic coating and a method for applying such a coating to a surface of a metallic substrate. The method can include anodizing a nanoporous layer of anodic metal oxide on the surface; cathodizing yttrium oxide nanoparticles onto the surface; applying a hydrophobic ceramic coating composition to the surface by an application method selected from the group consisting of: flowing, dipping, and spraying; and heating the coated surface at a cure temperature from about 150° C. to about 300° C. for at least 2 hours.
