Method for manufacturing a fire-resistant part of an air conditioning system for an air or rail transport vehicle, characterized in that it includes at least the following steps: a step of obtaining a part including at least one aluminum alloy surface portion, and a step of treating the aluminum alloy surface portion by use of micro-arc oxidation in order to produce a ceramic coating on the surface portion.

A method of localized repair to a damaged thermal barrier, the method including subjecting a part coated in a damaged thermal barrier to electrophoresis treatment, the part being made of an electrically conductive material, the damaged thermal barrier including a ceramic material and presenting at least one damaged zone that is to be repaired, the part being present in an electrolyte including a suspension of particles in a liquid medium, the ceramic coating being deposited by electrophoresis in the damaged zone in order to obtain a repaired thermal barrier for use at temperatures higher than or equal to 1000&#xb0; C., the particles being made of a material different from the ceramic material present in the damaged thermal barrier.
