PROCESS FOR LOCALISED REPAIR OF DAMAGED THERMAL BARRIER Russian patent published in 2019 - IPC C25D13/02 

FIELD: machine building.

SUBSTANCE: invention relates to a process for the localised repair of a damaged thermal barrier. Method includes 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, obtained by physical vapour deposition by an electron beam and has at least one damaged area to be repaired, the part being present in an electrolyte comprising a suspension of particles in a liquid medium, which in a non-agglomerated state have an average size of 40 nm to 1 mcm, where in the damaged area, a ceramic coating is deposited by electrophoresis to obtain a restored thermal barrier for use at temperatures higher than or equal to 1000 °C, and the particles are obtained from a material other than a ceramic material present in the damaged thermal barrier.

EFFECT: technical result: extension of the life of the parts.
