Abstract

ESTE INVENTO CUENTA CON UN METODO DE INTENSIFICAR LAS IMPRESIONES LINEALES EN LA SUPERFICIE DE UNA BANDA ACERO ELECTRICO ORIENTADAS GRANULADO, GRABANDO ELECTROLITICAMENTE DICHAS IMPRESIONES, POR EJEMPLO, CON ACIDO CITRICO. LAS IMPRESIONES PUEDEN SER FORMADAS POR EL TRAZADO DE RUEDAS MECANICAS O POR ABLACION DE LA SUPERFICIE POR EJEMPLO, DESCARGANDO UNA CHISPA O TRATAMIENTO LASER Y PUEDE SER CONTINUA O DISCONTINUA EN FORMA DE MARCHA O DE LINEAS. POR CONSIGUIENTE, DE ACUERDO CON ESTE INVENTO, LA GENERACION INICIAL DE IMPRESIONES LIGERAS EN BANDAS DE ACERO FORMADAS POR EL TRAZADO DE RUEDAS MECANICAS O POR TECNICAS DE ABLACION PUEDE SER FACILMENTE INTENSIFICADAS APLICANDO LA TECNICA DE GRABADO ELECTROLITICA PARA PRODUCIR UN MATERIAL CON VALORES DE PERDIDA DE ENERGIA (REDUCIDA DESDE EL VALOR ORIGINAL PERDIDO NO TRAZADO) QUE SON SUBSTANCIALMENTE RESISTENTES AL RECONOCIMIENTO. EN COMPARACION, ELMATERIAL TRAZADO CONVENCIONALMENTE NO MUESTRA RESISTENCIA AL RECONOCIMIENTO A ALTAS TEMPERATURAS POR LO QUE SE REFIERE A LA REDUCCION PERDIDA.
