Abstract
A substrate is protected by first providing the substrate, and applying a ceramic coating overlying and bonded to the substrate. The ceramic coating is formed of an open-cell solid foam of ceramic cell walls having an interconnected intracellular volume therebetween which is filled at least in part with a metallic alloy. The ceramic coating has an exposed surface remote from the substrate. The exposed surface of the ceramic coating is heated to an exposure temperature such that at least some of the metallic alloy is lost from the intracellular volume.
