PROCESS FOR LOCALISED REPAIR OF A DAMAGED THERMAL BARRIER

摘要

The invention relates to a process for the localised repair of a damaged thermal barrier comprising the following step: a) treatment via electrophoresis of a part coated with a damaged thermal barrier, the part being formed from an electrically conductive material, the damaged thermal barrier comprising a ceramic material and having at least one damaged zone to be repaired, the part being present in an electrolyte comprising a suspension of particles in a liquid medium, a ceramic coating being deposited by electrophoresis in the damaged zone in order to obtain a repaired thermal barrier intended to be used at temperatures greater than or equal to 1000°C, the particles being formed from a material different to the ceramic material present in the damaged thermal barrier.
