Abstract

Procedimiento para mejorar la resistencia aislante superficial de un acero eléctrico, que tiene sobre el mismo un revestimiento aislante primario, caracterizado porque comprende las etapas de utilizar dicho acero como ánodo y someter el acero a un tratamiento electroquímico en un electrolito del tipo que provocará la precipitación de un hidróxido metálico para separar las pequeñas partículas metálicas que se extienden a través de dicho revestimiento aislante o que sobresalen por encima del mismo.
