Abstract

EN UN METODO PARA PROPORCIONAR A PARTES DE ACERO REVESTIMIENTOS PROTECTORES QUE INCLUYE CAPAS SUCESIVAS DE ZINC Y CROMATO, LA CAPA DE ZINC SE APLICA MEDIANTE TRATAMIENTO GALVANOPLASTICO DE ZINC Y LAS PARTES SE LAVAN CON AGUA ANTES DE LA APLICACION DE LA CAPA DE CROMATO, EL TRATAMIENTO CONTINUO DE LAS PARTES INCLUYE: INMEDIATAMENTE DESPUES DEL LAVADO CON AGUA DE LAS PARTES GALVANIZADAS Y MIENTRAS LAS PARTES ESTAN AUN HUMEDAS, LA PULVERIZACION DE LAS PARTES CON UNA SOLUCION DE CROMACION ACUOSA QUE CONTIENE ACIDO CRONICO JUNTO CON ACIDO NITRICO Y AL MENOS UNA SAL QUE PROPORCIONA ANIONES ACTIVADORES, DICHA PULVERIZACION DE CROMACION HUMEDECE LAS SUPERFICIES EXTERIORES DE LAS PARTES Y SE COMPLETA EN NO MAS DE 120 SEGUNDOS CON LA FORMACION DE UNA CAPA DE CROMATO AMARILLO EN LAS PARTES.
