Abstract
A method for forming a cathodic protection coating on a substrate forming a turbomachine part, includes deposition, on the substrate, of particles for cathodic protection of the substrate, this deposition being performed by electrophoresis from an organic electrolyte including the particles, and forming an inorganic matrix in pores of the deposit of particles produced in this way, including impregnating the deposit with an impregnation composition, drying heat treatment of the deposit impregnated by the impregnation composition, and densifying the deposit by mechanical compacting, after the drying heat treatment, in order to make the deposit electrically conductive.
