Abstract

(A) UN PROCESO PARA FORMAR UN RECUBRIMIENTO DE CONVERSION DE COBALTO SOBRE UN SUSTRATO METALICO, IMPARTIENDO ASI UNA RESISTENCIA A LA CORROSION Y PROPIEDADES DE ADHESION DE PINTURA. LA INVENCION SE DESARROLLO PARA SUSTITUIR A LA MANERA EN QUE SE LLEVABA A CABO EL PROCESO ACIDO CROMATICO. EL PROCESO CONSISTE EN LOS PASOS SIGUIENTES: (A) PRODUCIR UNA SOLUCION DE CONVERSION DE COBALTO QUE CONTENGA UNA SOLUCION ACUOSA, ALCALINA, QUE CONTIENE UN COMPLEJO HEXAVALENTE DE COBALTO-III SOLUBLE, SIENDO LA CONCENTRACION DEL COMPLEJO HEXAVALENTE DE COBALTO-III DE 0,1 MOL APROXIMADAMENTE POR GALON DE SOLUCION AL LIMITE DE SATURACION DEL COMPLEJO HEXAVALENTE DE COBALTO-III; Y (B) PONER EN CONTACTO EL SUSTRATO CON LA SOLUCION DURANTE UN PERIODO DE TIEMPO SUFICIENTE, CON LO QUE SE FORMA EL RECUBRIMIENTO DE CONVERSION DE COBALTO. EL SUSTRATO PUEDE SER ALUMINIO O UNA ALEACION DE ALUMINIO ASI COMO CD PLATEADO, ZN PLATEADO, ZN-NI PLATEADO Y ACERO. EL COMPLEJO HEXAVALENTE DE COBALTO-III PUEDE ESTAR PRESENTE EN FORMA DE [CO-(NH SUB 3) SUB 6]X SUB 3 EN DONDE X ES CL, BR, NO SUB 3, CN, SCN, PO SUB 4, C SUB 2H SUB 3O SUB 2 O CO SUB 3. (B) UNA SOLUCION DE RECUBRIMIENTO DE CONVERSION QUIMICA PARA PRODUCIR EL RECUBRIMIENTO DE CONVERSION DE COBALTO SOBRE UN SUSTRATO METALICO, INCLUYENDO LA SOLUCION UNA SOLUCION ACUOSA, ALCALINA, QUE CONTIENE UN COMPLEJO HEXAVALENTE DE COBALTO-III SOLUBLE, SIENDO LA CONCENTRACION DEL COMPLEJO HEXAVALENTE DE COBALTO-III DE 0,1 MOL APROXIMADAMENTE POR GALON DE SATURACION AL LIMITE DE SATURACION DEL COMPLEJO HEXAVALENTE DE COBALTO-III. LA SOLUCION DE CONVERSION DE COBALTO SE PUEDE PREPARAR MEDIANTE UNA SECUENCIA DE FORMACION DEL BAÑO QUE CONSISTE EN LOS PASOS SIGUIENTES: (A) DISOLVER UNA SAL DE AMONIO; (B) DISOLVER A CONTINUACION UNA SAL DE COBALTO-II; Y (C) AÑADIR DESPUES HIDROXIDO DE AMONIO (AMONIACO). (C) UN ARTICULO RECUBIERTO QUE PRESENTA UNA RESISTENCIA A LA CORROSION Y PROPIEDADES DE ADHESION A LA PINTURA, CONSTANDO EL SUSTRATO DE: (A) UN SUSTRATO METALICO; Y (B) UN RECUBRIMIENTO DE CONVERSION DE COBALTO FORMADO SOBRE EL SUSTRATO, INCLUYENDO EL RECUBRIMIENTO DE CONVERSION DE COBALTO OXIDO DE ALUMINIO ALO SUB 3 COMO EL MAYOR PORCENTAJE DE VOLUMEN Y OXIDOS DE COBALTO COO, COO SUB 4 Y CO SUB 2O SUB 3 .
