Abstract

L'INVENTION CONCERNE LE TRAITEMENT D'UN OBJET CONTENANT TI POUR EN INHIBER LA CORROSION PAR FROTTEMENT. ON DEPOSE SUR CET OBJET, SOUS VIDE, UNE SUBSTANCE ACTIVE, DONT L'OXYDE EXIGE POUR SE FORMER PLUS DE CHALEUR QUE POUR TI, PUIS L'ON CHAUFFE SUFFISAMMENT L'OBJET POUR PROVOQUER LA MIGRATION DE LA SUBSTANCE ACTIVE DANS CET OBJET ET OBTENIR UNE REGION SUPERFICIELLE CONTENANT CETTE SUBSTANCE ACTIVE. DE PREFERENCE, LE DEPOT S'EFFECTUE PAR UNE TECHNIQUE DE BOMBARDEMENT IONIQUE. APPLICATION: PROTECTION DES SURFACES DE PORTEE, EN TI, D'OBJETS DESTINES AUX INDUSTRIES AEROSPATIALES ETOU POUR LE DOMAINE MEDICAL.
