Abstract

PROCEDIMIENTO PARA EL TRATAMIENTO DE UNA SUPERFICIE DE ZINC. PONER EN CONTACTO LA SUPERFICIE DE ZINC CON UN LIQUIDO DE TRATAMIENTO FORMADO POR UNA SOLUCION ACUOSA ALCALINA QUE TIENE UN PH ENTRE 7Y 11,0 Y CONTIENE 0,020 G/L DE IONES NI(2+) Y NH3 EN CANTIDAD SUFICIENTE PARA DAR UNA RELACION MOLAR DE HN3 A IONES NI(2+) EN LA SOLUCION DE POR LO MENOS 6. EL LIQUIDO DE TRATAMIENTO CONTIENE POR LO MENOS 1,0 G/L DE IONES NIQUEL. LA TEMPERATURA DEL LIQUIDO DE TRATAMIENTO DURANTE DEL CONTACTO ESTA ENTRE 20 A 50°C.PROCEDURE FOR THE TREATMENT OF A ZINC SURFACE. TO CONTACT THE ZINC SURFACE WITH A TREATMENT LIQUID FORMED BY A WATER ALKALINE SOLUTION THAT HAS A PH BETWEEN 7 AND 11.0 AND CONTAINS 0.020 G / L OF NI (2+) IONS AND NH3 IN ENOUGH AMOUNT TO GIVE A MOLAR RELATION FROM HN3 TO IONS NOR (2+) IN THE SOLUTION OF AT LEAST 6. THE TREATMENT LIQUID CONTAINS AT LEAST 1.0 G / L OF NICKEL IONS. THE TEMPERATURE OF THE TREATMENT LIQUID DURING THE CONTACT IS BETWEEN 20 TO 50 ° C.
