Claim Text:
1. A method of fabricating a thermal barrier comprising a ceramic coating layer covering at least a portion of a structure of a substrate, the method comprising: depositing the ceramic coating layer on the substrate solely by cathodic electrodeposition, and heat treating the ceramic coating layer and the substrate together for at least 10 minutes at a temperature of from 400° C. to 2000° C. under argon at atmospheric pressure in the presence of at least 0.0001 bar (10 Pa) of oxygen, wherein cathodic electrodeposition is with an electrolyte and is between an anode and the substrate, as a cathode, wherein the substrate comprises an electron-conducting material, the electrolyte comprises a lanthanide salt, a yttrium salt, a zirconium salt, a hafnium salt, or a combination thereof, and the coating layer comprises a lanthanide oxide, a yttrium oxide, a zirconium oxide, a hafnium oxide, or a combination thereof.
