Abstract
The invention relates to a method of fabricating a thermal barrier comprising a ceramic coating layer covering at least a portion of the structure of a substrate, wherein the ceramic coating layer is deposited on the substrate solely by a cathodic electrodeposition process between at least one cathode () and at least one anode (), the substrate being formed of an electron-conducting material and constituting the cathode. In characteristic manner, the electrolyte () comprises at least one salt from the group comprising the salts of lanthanides, of yttrium, of zirconium, and of hafnium, such that the coating layer applied by the electrodeposition process includes at least one oxide from the group comprising the oxides of lanthanides, of yttrium, of zirconium, and of hafnium, and it also includes a step of heat treating the ceramic coating layer at a temperature lying in the range 400° C. to 2000° C. for a duration of at least 10 min.
