Abstract

UN METODO DE MEJORAR LA RESISTENCIA A LA CORROSION DE UN ACERO INOXIDABLE SINTERIZADO.SE PONEN EN CONTACTO LAS SUPERFICIES INTERIORES, POR LO MENOS PARCIALMENTE ACTIVADAS, DEL ACERO INOXIDABLE SINTERIZADO, CON UNA SOLUCION QUE CONTIENE FOSFATO EN UNA SOLUCION ACUOSA; DICHA SOLUCION QUE CONTIENE FOSFATO, ES UNA SOLUCION DE PIROFOSFATO SODICO O DE ORTOFOSFATO TRISODICO. ANTES DE DICHO TRATAMIENTO, EL ACERO INOXIDABLE, SE TRATA CON UNA SOLUCION ACIDA ACUOSA DE ACIDO ACETICO, HASTA ACTIVAR LAS SUPERFICIES EXTERIORES. EL TRATAMIENTO CON LA SOLUCION QUE CONTIENEFOSFATO SE REPITE PERIODICAMENTE.
