Abstract
La presente invención se refiere a método mejorado para producir un material compuesto eléctricamente conductor, caracterizado por un primer metal y un óxido de un segundo metal, cuyo método incluye los pasos de proporcionar el primer metal en forma de polvo; proporcionar el óxido del segundo metal en forma de polvo; mezclar los polvos juntos en las proporciones deseadas mediante un mezclado en tambor giratorio en seco, efectuándose el mezclado del polvo en dos etapas, tamizándose los polvos mezclados entre las dos etapas de mezclado; consolidar la mezcla de polvo bajo presión en un cuerpo compacto de polvo poroso; calentar el cuerpo compacto de polvo poroso en una atmósfera reductora para proporcionar un cuerpo de aleación poroso que consiste de una solución sólida del segundo metal en el primer metal; calentar el cuerpo de aleación poroso a una temperatura dentro de la escala de 180ºC. hasta la temperatura de fusión de la aelación, en una atmósfera oxidante, para efectuar la reoxidación del segundo metal; y opcionalmente prensar el cuerpo de aleación poroso internamente oxidado para aumentar la densidad del mismo; sisterizar el cuerpo prensado para proporcionar una microestructura deseada para el cuerpo a una temperatura de 930ºC. durante una hora, ya sea en aire o nitrógeno; y troquelar a presión el cuerpo de aleación sinterizado para aumentar más la densidad del mismo.The present invention relates to an improved method of producing an electrically conductive composite material characterized by a first metal and a second metal oxide, the method of which includes the steps of providing the first metal in powder form; providing the oxide of the second metal in powder form; mixing the powders together in the desired proportions by dry rotary drum mixing, mixing the powder in two stages, sifting the mixed powders between the two mixing stages; consolidate the powder mixture under pressure into a compact porous powder body; heating the compact body of porous powder in a reducing atmosphere to provide a porous alloy body consisting of a solid solution of the second metal in the first metal; heat the porous alloy body to a temperature within the scale of 180 ° C. up to the fusion temperature of the aelation, in an oxidizing atmosphere, to effect the reoxidation of the second metal; and optionally pressing the internally oxidized porous alloy body to increase its density; sisterize the pressed body to provide a desired microstructure for the body at a temperature of 930ºC. for one hour, either in air or nitrogen; and die-cutting the sintered alloy body to further increase its density.
