Abstract

"ELETRODO DE FIO COM UMA SUPERFìCIE DE INTERFACE ESTRUTURADA". A fim de se obter uma redução no desgaste dos cilindros de guia de fio, além de um aperfeiçoamento na velocidade de corte e de um aperfeiçoamento na condução de corrente, um eletrodo de fio para o corte de metais, etc. por erosão de faísca, compreendendo um centro homogêneo (1) feito de um metal ou de uma liga de metal, ou um centro compósito, é provido com uma cobertura de revestimento (2) cuja superfície é estruturada, no qual os entalhes (3) criados pela estrutura são enchidos por um agente de enchimento (4) feito de um metal facilmente vaporizável ou de uma liga de metal, de modo a se obter uma superfície com uma pequena altura do pico ao vale, isto é, com uma pequena aspereza de superfície.
