Abstract

PROCÉDÉ DE PROTECTION CONTRE L’OXYDATION D’UN MATÉRIAU POREUX L’invention concerne un procédé de protection contre l’oxydation d’une pièce en matériau poreux, comprenant au moins : - une étape d’imprégnation (10) de la porosité interne de la pièce par une composition d’imprégnation comprenant un fluide vecteur, un agent mouillant, et une poudre de verre de protection contre l’oxydation ; puis - une étape de colonisation d’une porosité du matériau poreux par le verre en réalisant un traitement thermique (30) permettant la fusion de la poudre de verre présente dans la porosité interne du matériau poreux et l’élimination du fluide vecteur ; et dans lequel le verre présente une viscosité dynamique inférieure ou égale à 1500 mPa.s au cours du traitement thermique.
