Abstract

UN METODO PARA INHIBIR LA CORROSION DE UNA SUPERFICIE METALICA EN UN SISTEMA ACUOSO QUE TIENE UN PH DE AL MENOS 6, QUE CONSISTE EN MANTENER EN EL SISTEMA ACUOSO, EN UNA CANTIDAD EFECTIVA COMO PARA INHIBIR LA CORROSION, UN QUELATO DE TIERRAS RARAS ORGANICO, SOLUBLE EN AGUA QUE SE DERIVA DE UN METAL DE LAS TIERRAS RARAS QUE TIENE UN NUMERO ATOMICO DEL 57 AL 71 Y UN QUELANTE ORGANICO. EL QUELANTE ORGANICO NO SOLO PROPORCIONA UNA SOLUBILIDAD EN AGUA SINO QUE SORPRENDENTEMENTE AUMENTA LA ACTIVIDAD INHIBIDORA DE LA CORROSION. LOS QUELATOS DE TIERRAS RARAS ORGANICOS, SOLUBLES EN AGUA SE PUEDEN COMBINAR DE MANERA VENTAJOSA CON OTRO INHIBIDORES DE LA CORROSION TALES COMO QUELATOS DE CINC, ORGANOFOSFATOS, FOSFATOS, CROMATOS, MOLIBDATOS Y SIMILARES.
