Abstract

PROCEDIMIENTO PARA LA FABRICACION DE MATERIALES PARA CONTACTOS ELECTRICOS. SE MEZCLA DE 50 A 99% EN VOLUMEN DE POLVO DE METAL NOBLE, TAL COMO ORO, PLATA Y/O PALADIO O SUS ALEACIONES, CON 1 A 50% EN VOLUMEN DE POLVO DE FRITA DE VIDRIO, QUE TIENE UNA TEMPERATURA DE TRANSFORMACION DE 400 A 750 C Y UN INTERVALO DE REBLANDECIMIENTO MAYOR DE 100 C. SE PRENSA LA MEZCLA DE POLVOS A TEMPERATURA AMBIENTE CON PRESIONES DE 500 A 5.000 BARES. SE SINTERIZA LA PIEZA PRENSADA A UNA TEMPERATURA DE 500 A 950 C Y FINALMENTE SE PRENSA EN CALIENTE EL CUERPO CONFORMADO A TEMPERATURAS DE 500 A 800 C Y PRESIONES DE 100 A 200 BARES.
