Abstract
PROCEDIMIENTO DE DEPOSICION DE UN REVESTIMIENTO DE CONVERSION A BASE DE OXIDO DE ALUMINIO HIDRATADO SOBRE UN SUSTRATO DE ALUMINIO, MAGNESIO, ESTAÑO O ZINC. CONSISTE EN PONER EL SUSTRATO A REVESTIR CON UNA SOLUCION ACUOSA DE AL+++, A UNA CONCENTRACION AL MENOS DE 0,05 G/E: TENIENDO LA SOLUCION UN PH DE 1,5 A 5,5 E INCLUYENDO IONES NITRATO COMO AGENTES DESPOLARIZANTES PARA LA REACCION ENTRE LA SOLUCION Y LA SUPERFICIE DEL SUSTRATO. LA SOLUCION O BIEN CONTIENE FLUORURO O EL SUSTRATO ESTA PREVIAMENTE TRATADO CON UNA SOLUCION ACUOSA DE FLUORURO PARA ELIMINAR LA CAPA SUPERFICIAL DE OXIDO DE ALUMINIO O SUSTRATO PARA FACILITAR LA DEPOSICION DEL REVESTIMIENTO.
