Abstract
Est concerné un procédé de protection, pour protéger d’une oxydation et/ou d’une corrosion au moins une zone interne creuse (13, 14) d’une pièce (2) de turbomachine en un superalliage, ladite au moins une zone interne creuse ayant été formée, par l’intermédiaire d’au moins un noyau en matériau céramique limité par une surface extérieure (26) qui l’entoure, caractérisé en ce qu’avant d’apporter le superalliage autour du noyau en matériau céramique, on revêt ladite surface extérieure avec un matériau comprenant au moins :- une couche nanométrique d’hafnium (Hf), et/ou- une couche micronique de platine (Pt), ou - un mélange au moins d’hafnium et de platine.
