Abstract

METODO DE PREPARACION DE UN RECUBRIMIENTO DE FOSFATO SOBRE SUSTRATOS METALICOS CORROIBLES.COMPRENDE: A) HACER REACCIONAR AL SUSTRATO CON UNA SOLUCION DE FOSFATO QUE CONTIENE NI2B, CO2B O MN2B, CUYOS HIDROXIDOS TIENEN UNA SOLUBILIDAD EN SOLUCION ALCALINA MENOR QUE LA DEL HIDROXIDO DE ZN Y ZN2B, A UNA TEMPERATURA ENTRE 38 Y 60JC, A UN PH DE 2,5 A 3,5 Y DURANTE 30 S A 2 MIN, PARA FORMAR UN RECUBRIMIENTO DE FOSFATO QUE CONTIENE 15 MOLES DE (NI2B, CO2B O MN2B), CALCULADO SOBRE EL TOTAL DE CATIONES METALICOS DIVALENTES Y 25 EN PESO DE ZN2B CALCULADO SOBRE EL PESO DE RECUBRIMIENTO, SOBRE EL SUSTRATO; Y B) SEPARAR AL SUSTRATO CON EL RECUBRIMIENTO, DE LA SOLUCION DE FOSFATO.
