Abstract

CETTE INVENTION CONCERNE DES PRODUITS REFRACTAIRES POREUX RESISTANT A UNE DEGRADATION AUX TEMPERATURES ELEVEES, PAR EXEMPLE PAR L'OXYGENE, LE CHLORE ET ANALOGUES. CES PRODUITS SONT CONSTITUES PAR UN CORPS PRINCIPAL EN CARBURE, NITRURE, BORURE OU SILICIURE FRITTE POREUX, QUI EST RECOUVERT DE NITRURE DE SILICIUM OU D'OXYNITRURE DE SILICIUM. LE REVETEMENT EST APPLIQUE NON SEULEMENT SUR LE CORPS PRINCIPAL DU PRODUIT REFRACTAIRE POREUX, MAIS IL PENETRE EGALEMENT DANS CE PRODUIT JUSQU'A UNE PROFONDEUR SUPERIEURE A LA PROFONDEUR DES PORES SUPERFICIELS. CES PRODUITS SONT UTILISABLES NOTAMMENT COMME ELEMENTS CHAUFFANTS TRAVAILLANT DANS UN MILIEU HOSTILE A UNE TEMPERATURE ELEVEE.
