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.IN A METHOD FOR PROVIDING STEEL PARTS WITH PROTECTIVE COATINGS INCLUDING SUCCESSIVE LAYERS OF ZINC AND CHROMATE, THE ZINC COAT IS APPLIED BY GALVANOPLASTIC TREATMENT OF ZINC AND THE PARTS ARE WASHED WITH WATER BEFORE THE APPLICATION OF THE COAT. CONTINUOUS PARTS INCLUDE: IMMEDIATELY AFTER WASHING OF THE GALVANIZED PARTS AND WHILE THE PARTIES ARE STILL WET, THE SPRAYING OF THE PARTS WITH A WATER CHROME SOLUTION CONTAINING A CHRONIC ACID AND ALSO A NITTEN ACID ACTIVATING ANIONS, SUCH CHROME SPRAY WET THE EXTERIOR SURFACES OF THE PARTS AND COMPLETE IN NO MORE THAN 120 SECONDS WITH THE FORMATION OF A YELLOW CHROME LAYER ON THE PARTS.
