Abstract

LA PRESENTE INVENTION CONCERNE UNE METHODE DE NITRURATION IONIQUE DES ACIERS DEFORMES PLASTIQUEMENT AU PREALABLE. CETTE METHODE EST CARACTERISEE PAR LA SUCCESSION DES QUATRE PHASES SUIVANTES: A.UNE OPERATION D'ECROUISSAGE PREALABLE DE LA PIECE, DONT LE TAUX FINAL D'ECROUISSAGE EST COMPRIS ENTRE 10 ET 40; B.UNE PREMIERE SEQUENCE DE NITRURATION IONIQUE, DE DUREE COMPRISE ENTRE UNE HEURE ET 10 HEURES SELON LA NATURE DE L'ACIER A TRAITER, REALISEE A UNE TEMPERATURE T1 COMPRISE ENTRE 450 ET 520 C DANS UN MELANGE GAZEUX CONSTITUE PAR DE L'AZOTE ET DE L'HYDROGENE, TEL QUE LA PRESSION PARTIELLE D'AZOTE P1 SOIT COMPRISE ENTRE 10 ET 35 PASCALS, ET QUE LA PRESSION GAZEUSE TOTALE SOIT COMPRISE ENTRE 200 ET 650 PASCALS; C.UNE DEUXIEME SEQUENCE DE NITRURATION IONIQUE, DE DUREE COMPRISE ENTRE 20 ET 70 HEURES SELON LA NATURE DE L'ACIER A TRAITER, REALISEE A UNE TEMPERATURE T2 COMPRISE ENTRE 500C ET 580C ET SUPERIEURE A T1 D'AU MOINS 10 C, DANS UN MELANGE GAZEUX CONSTITUE PAR DE L'AZOTE ET DE L'HYDROGENE, TEL QUE LA PRESSION PARTIELLE D'AZOTE P2 SOIT COMPRISE ENTRE 20 ET 100 PASCAL, ET SOIT SUPERIEURE A P1, TANDIS QUE LA PRESSION GAZEUSE TOTALE RESTE COMPRISE ENTRE 200 ET 650 PASCALS; D.UN REFROIDISSEMENT FINAL SOUS VIDE. CETTE METHODE EST APPLICABLE AUX ACIERS DE TOUTES NUANCES, DEPUIS LES ACIERS PEU ALLIES JUSQU'AUX ACIERS INOXYDABLES ET AUX ACIERS REFRACTAIRES.
