Abstract

Mejoras en los procedimientos de preparación de electrodos caracterizadas porque comprenden el disponer el referido electrodo adyacente a un miembro metálico en un vacio y aplicar una tensión entre el referido electrodo y el referido miembro de un valor tal que se produzca un chisporreteo entre ellos y para quemar proyecciones diminutas en la superficie del referido electrodo.Improvements in the procedures for preparing electrodes characterized in that they comprise placing said electrode adjacent to a metal member in a vacuum and applying a voltage between said electrode and said member of a value such that sparking occurs between them and to burn tiny projections on the surface of the referred electrode.
