Abstract

L'invention concerne une composition de métal en poudre pour des applications de résistance élevée à l'usure et à la température qui est fabriquée par atomisation d'un alliage à base de fer fondu comprenant 3,0 à 7,0 % en poids de carbone; 10,0 à 25,0 % en poids de chrome; 1,0 à 5,0 % en poids de tungstène; 3,5 à 7,0 % en poids de vanadium; 1,0 à 5,0 % en poids de molybdène; pas plus de 0,5 % en poids d'oxygène; et au moins 40,0 % en poids de fer. La teneur en carbone élevée réduit la solubilité de l'oxygène dans la fonte et donc diminue la teneur en oxygène à un niveau au-dessous duquel on amènerait les éléments de formation de carbure à s'oxyder pendant l'atomisation. La composition de métal en poudre comprend des carbures métalliques dans une quantité d'au moins 15 % en volume. La micro-dureté de la composition de métal en poudre augmente avec des quantités croissantes de carbone et est typiquement environ 800 à 1 500 Hv50.
