Abstract

PARTICULARMENTE EN APOYOS DE CONTACTO DE UN MATERIAL A BASE DE PLATA-OXIDO METALICO (AGMLO), EN EL CUAL LOS APOYOS DE CONTACTO EN SUS LATERALES TRASEROS ESTAN DOTADOS CON SOLDADURA, QUE SE OBSERVA JUNTO A LA SOLDADURA FUERTE EN UN SOPORTE DE CONTACTO, YA QUE LA SOLDADURA EN UN MODO NO DESEADO PUEDE AUMENTAR MUCHO EN LA SUPERFICIE DE CONTACTO. POSTERIORMENTE SE EXPLICA A TRAVES DEL CALENTAMIENTO JUNTO A LA SOLDADURA FUERTE. CON ARREGLO A LA INVENCION SE EMPEORA EL ROCIADO DEL APOYO DE CONTACTO EN LA SUPERFICIE LATERAL, YA QUE SE EVITA EL AUMENTO ELEVADO DE LA SOLDADURA EN LA SUPERFICIE DE CONTACTO. PREFERENTEMENTE SE PRODUCE OXIDO METALICO EN LA SUPERFICIE DE APOYO DE CONTACTO. JUNTO AL APOYO DE CONTACTO A BASE DE OXIDO METALICO-PLATA PUEDEN UTILIZARSE PREFERENTEMENTE OXIDO METALICO SEMEJABLE QUE SIEMPRE ESTAN PRESENTES COMO COMPONENTES ACTIVOS EN EL MATERIAL.
