Abstract
Methods for the fabrication of strongly adherent ceramic (e.g., titanium oxide such as TiO2) coatings on porous metallic substrates includes forming a first coating comprising metal particles on a surface of the porous metallic substrate, followed by forming a second coating comprising ceramic particles on the first coating. A porous coated metallic substrate assembly formed by the method includes a first sinter-bonded coating layer on a surface of a porous metallic substrate, the first sinter-bonded coating layer comprising metal particles from a coating composition, and a second sinter-bonded coating layer on the first porous coating layer, the second sinter-bonded coating layer comprising metal oxide particles from a coating composition.
