Abstract

BANDA (16) IMPREGNADA DE GRANO ELECTRICAMENTE ORIENTADO CON DOMINIO PERMANENTE DE REFINADO SE OBTIENE A GRAN VELOCIDAD EN UN PROCESO DE DOS ETAPAS. EL PROCESO ELIMINA EL CRISTAL EN LAS REGIONES (17) ESTRECHAS EN LAS CUALES SE DESCUBRE EL METAL BASE. UN GRABADO ELECTROLITICO SE USA ENTONCES PARA PROFUNDIZAR EN LAS REGIONES (17) DENTRO DEL METAL BASE Y SE MINIMIZAN LOS DAÑOS A LA CAPA DE CRISTAL REMANENTE. EL CONTROL DE LA CONCENTRACION DE ACIDO Y DE LA TEMPERATURA EN LA CUBA ELECTROLITICA PERMITEN UN MAYOR INCREMENTO DE LA PRODUCTIVIDAD. UNA CARACTERISTICA ADICIONAL DEL PROCESO ES LA MEDIDA DE LA PERMEABILIDAD PARA OPTIMIZAR LA PROFUNDIDAD DE LAS REGIONES GRABADAS. LA PARTE PROFUNDA MEJORADA PRODUCIDA POR EL PROCESO SOBREVIVIRA AL RECOCIDO DEL RELIEVE CIRCUNDANTE.FIG 1.
