Abstract

Procedimiento para la fabricación de una pieza de contacto de plata y por lo menos dos óxidos de metales innobles, para contactos eléctricos con pequeña fuerza de soldadura y al mismo tiempo bajo desgaste por arco voltáico, caracterizado porque se fabrica a partir de una fusión de plata y por lo menos dos metales innobles, por inyección a presión y oxidación interna un polvo compuesto, y se da al polvo compuesto la forma de la pieza mediante prensado, sinterizado y nuevo prensado, donde dichos metales innobles son cadmio y bismuto y/o plomo, estableciéndose el contenido de óxidos de metal innoble en la pieza moldeada se halla por debajo del 20% de volumen, y donde el medio de arrastre para la inyección a presión de la fusión es agua.
