Abstract

EN LA INVENCION SE TRATA DE UN PROCEDIMIENTO CONTINUO, EN EL CUAL SE COLOCA UNA PATINA SOBRE LA SUPERFICIE DE UN MATERIAL DE COBRE BAJO EN GRASAS Y CON UNA PROFUNDIDAD DEFINIDA DE ASPEREZAS. EL MATERIAL PARA ELLO SE SOMETE A UNA ANODIZACION EN UN BAÑO EN MOVIMIENTO DE ELECTROLISIS QUE CONTIENE UN CARBONATO SODICO Y/O BICARBONATO SODICO ASI COMO SULFITO SODICO Y/O DISULFITO SODICO, EL BAÑO CON UNA TEMPERATURA DE 30 C A 90 C Y UNA DENSIDAD DE CORRIENTE DE 1 A/DM{SUP,2} DURANTE UN TIEMPO DE PERMANENCIA DE 10 SEGUNDOS A 12 MINUTOS. A CONTINUACION SE LAVA EL MATERIAL Y SE SOMETE A UN BAÑO DE FIJACION QUE CONTIENE AL MENOS UNO DE LOS SIGUIENTES OXIDANTES: PEROXIDO DE HIDROGENO (H{SUB,2}O{SUB,2}), CLORATO POTASICO (KCLO{SUB,3}), PEROXODISULFATO POTASICO (K{SUB,}S{SUB,2}O{SUB,8}), PERMANGANATO POTASICO (KMNO{SUB,4}), O SULFATO CUPRICO (CUSO{SUB,4}.5H{SUB,2}O), A UNA TEMPERATURA DE 35 IA DE 10 SEGUNDOS HASTA 120 SEGUNDOS, Y FINALMENTE SE SECA DESPUES DE OTRO LAVADO.
