Abstract
(A) UN PROCESO PARA FORMAR UN REVESTIMIENTO DE CONVERSION DE COBALTO SOBRE UN SUSTRATO DE METAL, CON LO QUE SE IMPARTE PROPIEDADES DE ADHESION A LA PINTURA Y RESISTENCIA A LA CORROSION. LA INVENCION FUE DESARROLLADA COMO UNA SUSTITUCION DEL ANTIGUO PROCESO DE ACIDO CROMICO. EL PROCESO COMPRENDE LOS PASOS DE: A) PREVER UNA SOLUCION DE CONVERSION DE COBALTO QUE COMPRENDE UNA SOLUCION ACUOSA QUE CONTIENE UN COMPLEJO HEXAVALENTE III DE COBALTO SOLUBLE SIENDO EL COMPLEJO HEXAVALENTE III DE COBALTO DE 0.01 MOL POR LITRO DE SOLUCION AL LIMITE DE SOLUBILIDAD DEL COMPLEJO HEXAVALENTE III DE COBALTO; Y B) PONER EN CONTACTO EL SUSTRATO CON LA SOLUCION PARA UNA CANTIDAD SUFICIENTE DE TIEMPO, CON LO QUE SE FORMA EL REVESTIMIENTO DE CONVERSION DE COBALTO. EL SUSTRATO PUEDE SER ALUMINIO O ALEACION DE ALUMINIO, ASI COMO CD CHAPADO, ZN CHAPADO, ZN-NI CHAPADO, Y ACERO. EL COMPLEJO HEXAVALENTE III DE COBALTO PUEDE ESTAR PRESENTE EN LA FORMA DE MEM[CO(R)6)N, DONDE ME ES NA, LI, K, CA, ZN, MG O MN, Y DONDE M ES2 O 3, N ES 1 O 2, Y R ES CARBOXILATO QUE TIENE DE 1 A 5 ATOMOS DE CARBONO. (B) UNA SOLUCION DE REVESTIMIENTO DE CONVERSION QUIMICA PARA PRODUCIR EL REVESTIMIENTO DE CONVERSION DE COBALTO SOBRE UN SUSTRATO DE METAL, COMPRENDIENDO LA SOLUCION UNA SOLUCION ACUOSA QUE CONTIENE UN COMPLEJO HEXAVALENTE III DE COBALTO SOLUBLE, SIENDO LA CONCENTRACION DEL COMPLEJO HEXAVALENTE III DE COBALTO DE APROXIMADAMENTE.01 MOL POR LITRO DE SOLUCION AL LIMITE DE SOLUBILIDAD DEL COMPLEJO HEXAVALENTE III DE COBALTO. (C) UN ARTICULO REVESTIDO QUE EXHIBE PROPIEDADES DE ADHESION DE PINTURA Y RESISTENCIA A LA CORROSION, COMPRENDIENDO EL ARTICULO: (A) UN SUSTRATO DE METAL; Y B) UN REVESTIMIENTO DE CONVERSION DE COBALTO FORMADO SOBRE EL SUSTRATO, COMPRENDIENDO EL REVESTIMIENTO DE CONVERSION OXIDO DE ALUMINIO AL2O3 COMO EL MAYOR PORCENTAJE DE VOLUMEN, Y OXIDOS DE COBALTO COO, COO2O3 Y COO4.
