Abstract

TRAITEMENT THERMIQUE DE PIECES EN ACIER, CONSISTANT A CHAUFFER CES DERNIERES SOUS PRESSION NORMALE, EN ATMOSPHERE CONTROLEE, OU LA PRESSION PARTIELLE D'OXYGENE EST MAINTENUE TELLE QUE: LE FER N'EST PAS OXYDE OU SEULEMENT PARTIELLEMENT SANS FORMATION DES OXYDES SUPERIEURS, LES ELEMENTS GENANTS TELS QUE LE C, LE MN, LE P, LE SI, L'AL ETC., SONT TOTALEMENT OXYDES. LA DUREE DU TRAITEMENT EST TELLE QUE L'OXYDATION DES ELEMENTS GENANTS EST EFFECTUEE DANS TOUTE UNE COUCHE D'OXYDATION INTERNE DE FAIBLE EPAISSEUR, SANS FORMER DE COUCHE SENSIBLEMENT CONTINUE D'OXYDE EN SURFACE. CE TRAITEMENT S'APPLIQUE DE FACON PARTICULIEREMENT AVANTAGEUSE AUX PIECES DESTINEES A SUBIR UN RECOUVREMENT SUPERFICIEL PAR UNE AUTRE SUBSTANCE: DEPOT METALLIQUE PAR IMMERSION DANS UN BAIN DE METAL FONDU OU EMAILLAGE.
