Abstract

SE DESCRIBE UN PROCESO POLVOMETALURGICO PARA PRODUCIR UN SEMIPRODUCTO PARA CONTACTOS ELECTRICOS A PARTIR DE UN MATERIAL COMPUESTO A BASE DE PLATA CON HIERRO. EL MATERIAL COMPUESTO CONSTA DE 5-50% DEL PESO DE HIERRO COMO PRIMER SUBCOMPONENTE Y DE 0-5% DEL PESO COMO SEGUNDO SUBCOMPONENTE, POR UNO O VARIOS DE LOS METALES TITANIO, CIRCONIO, NIOBIO, TANTALIO, MOLIBDENO, WOLFRAMIO, MANGANESO Y CINC Y/O SUS OXIDOS Y/O SUS CARBUROS Y EL RESTO, PLATA COMO COMPONENTE PRINCIPAL. EN PRIMER LUGAR SE ELABORA A PARTIR DE AL MENOS DOS COMPONENTES DISTINTOS DEL MATERIAL COMPUESTO, SIENDO UNO DE ELLOS PLATA O HIERRO UN POLVO COMPUESTO O -SI ES POSIBLE- UN POLVO DE ALEACION, EN ESPECIAL POR EL PROCESO DE PIROLISIS CHISPORROTEANTE. ESTO SE MEZCLA A CONTINUACION CON LOS RESTANTES COMPONENTES EN POLVO, SE COMPRIME Y SE SINTERIZA.
