Abstract

LA INVENCION SUMINISTRA UN PROCEDIMIENTO PARA LIMPIAR UNA SUPERFICIE DE METAL QUE COMPRENDE LOS PASOS DE: A) PONER EN CONTACTO LA SUPERFICIE DE METAL CON UNA SOLUCION LIMPIADORA ALCALINA PARA ELIMINAR LOS CONTAMINANTES TALES COMO LA SUCIEDAD Y LA GRASA; Y B) PONER EN CONTACTO LA SUPERFICIE DE METAL CON UNA SOLUCION LIMPIADORA, ACIDICA QUE CONTIENE IONES DE TIERRAS RARAS MEDIANTE LO CUAL SE ELIMINA LA SUCIEDAD FORMADA SOBRE LA SUPERFICIE DE METAL MEDIANTE EL PASO A). EL PROCESO PUEDE UTILIZARSE PARA PREPARAR UNA SUPERFICIE DE METAL PARA UN PROCESO DE RECUBRIMIENTO SUBSECUENTE QUE INCLUYA EL PASO ADICIONAL DE: PONER EN CONTACTO LA SUPERFICIE DE METAL CON UNA SOLUCION DE RECUBRIMIENTO ACIDICA QUE CONTENGA IONES DE TIERRAS RARAS INCLUYENDO CATIONES DE TIERRAS RARAS CAPACES DE TENER MAS DE UN ESTADO DE VALENCIA, DANDO COMO RESULTADO EL INCREMENTO DEL PH DE LA SOLUCION DE RECUBRIMIENTO EN LA REGION DE LA SUPERFICIE DEL METAL HASTA UN VALOR SUFICIENTE PARA PRECIPITAR UNO O MAS COMPUESTOS DEL ELEMENTO DE TIERRAS RARAS, PARA DE ESTA FORMA PROVOCAR QUE EL COMPUESTO DEL ELEMENTO DE TIERRAS RARAS SE PRECIPITE EN UN REVESTIMIENTO SOBRE LA SUPERFICIE DEL METAL. LA INVENCION TAMBIEN SUMINISTRA UNA SOLUCION LIMPIADORA, ACUOSA, ACIDICA QUE CONTIENE IONES DE TIERRAS RARAS PARA SU USO EN EL PASO B) DEL PROCESO DE LA INVENCION, LA SOLUCION INCLUYE IONES DE UNO O MAS ELEMENTOS DE TIERRAS RARAS EN UNA CANTIDAD EFECTIVA PARA ELIMINAR LA SUCIEDAD DE LA SUPERFICIE DEL METAL PREVIAMENTE PUESTA EN CONTACTO CON UNA SOLUCION LIMPIADORA ALCALINA. LA INVENCION TAMBIEN SE EXTIENDE A UNA SUPERFICIE DE METAL, TRATADA POR EL PROCESO DE LA INVENCION.
