Abstract

L'invention concerne l'industrie métallurgique et électrique. Pour améliorer les caractéristiques électriques de matériaux de contact électrique en alliage Ag-Sn ayant subi une oxydation interne, on le combine avec d'autres alliages d'argent contenant des éléments métalliques en solution solide avec l'argent et susceptibles d'une oxydation interne; les composés obtenus sont constitués de matrices d'argent granulaires contenant des oxydes d'étain et d'autres matrices d'argent granulaires contenant les oxydes métalliques correspondant aux autres alliages d'argent et présentant une intercoalescence entre eux et avec les premières matrices d'argent granulaires et possédant, du point de vue macroscopique, des caractéristiques électriques améliorées semblables à celles qu'ils possèderaient s'ils étaient constitués d'un alliage unique. Application notamment à la réalisation de contacts électriques de caractéristiques améliorées telles que la résistance de contact, au collage et à l'usure.
