PROCEDE DE PRODUCTION D'UNE MATIERE METALLIQUE A DEUX OU PLUSIEURS PHASES, ET MATIERE OBTENUE.LA MATIERE CONSISTE EN DES PARTICULES D'UNE PHASE A POINT ELEVE DE FUSION (FER OU FONTE) DISPERSEES DANS UNE MATRICE (ALUMINIUM) A PLUS BAS POINT DE FUSION. LA MATIERE DES PARTICULES EST SOLUBLE DANS LA MATRICE AU POINT DE FUSION DE CELLE-CI, MAIS LA MATIERE OBTENUE NE MANIFESTE PAS DE DISSOLUTION DES PARTICULES. DANS UN COURANT 6 DE LA MATIERE DE MATRICE FONDUE, PULVERISEE (GAZ 10, 8, 7), ON INTRODUIT LES PARTICULES 11 ET L'ON DIRIGE LA PULVERISATION SUR UNE SURFACE PLUS FROIDE 14 POUR SOLIDIFIER ET FORMER LA MATIERE A PHASES MULTIPLES 13. LA TEMPERATURE DE LA PULVERISATION EST INFERIEURE AU POINT DE FUSION DES PARTICULES.APPLICATION: MATIERES DE FRICTION (GARNITURE DE FREIN).
