Zusammenfassung:	Process and device for depositing metallic protective coatings on various shaped articles, the coating being obtained in two successive additions. The first addition is performed by an electrophoresis operation using as electrode a grid 5 made up of conductive rods 6 whose distance apart is calculated as a function of the desired thicknesses over the various regions of the article 1-2. Application to the protection of turbine blades against oxidation and corrosion. PROCEDE ET DISPOSITIF POUR DEPOSER DES REVETEMENTS PROTECTEURS METALLIQUES SUR DES PIECES DE FORME DIVERSES, LE REVETEMENT ETANT OBTENU EN DEUX APPORTS SUCCESSIFS.LE PREMIER APPORT EST EFFECTUE PAR UNE OPERATION D'ELECTROPHORESE EN UTILISANT COMME ELECTRODE UNE GRILLE 5 FORMEE DE BARRES CONDUCTRICES 6 DONT L'ECARTEMENT EST CALCULE EN FONCTION DES EPAISSEURS SOUHAITEES SUR LES DIVERSES ZONES DE LA PIECE 1-2.APPLICATION A LA PROTECTION CONTRE L'OXYDATION ET LA CORROSION DES AUBES DE TURBINE.
