Abstract
(A.) UN PROCESO PARA FORMAR UNA CAPA DE CONVERSION DE COBALTO SOBRE UN SUSTRATO METALICO, PARA IMPARTIRLE PROPIEDADES DE RESISTENCIA A LA CORROSION Y DE ADHESION DE LA PINTURA. LA INVENCION FUE DESARROLLADA COMO SUSTITUTO PARA EL PROCESO DE ACIDO CROMICO ANTERIOR. EL PROCESO INCLUYE LOS PASOS DE: (A) PROPORCIONAR UNA SOLUCION DE CONVERSION DEL COBALTO QUE COMPRENDE UNA SOLUCION LIQUIDA PROVISTA DE UN PH DE ALREDEDOR DE 7.0 A 7.2 Y QUE CONTIENE UN COMPLEJO HEXACOORDINADO DE COBALTO-III SOLUBLE, LA CONCENTRACION DE DICHO COMPLEJO ES DE ALREDEDOR DE 0.1 MOLECULAS POR GALON DE LA SOLUCION HASTA EL LIMITE DE SATURACION DEL COMPLEJO; Y (B) PONER EN CONTACTO EL SUSTRATO CON LA SOLUCION DURANTE EL TIEMPO SUFICIENTE PARA QUE SE FORME LA CAPA DE CONVERSION DEL COBALTO. EL SUSTRATO PODRA SER DE ALUMINIO O DE UNA DE SUS ALEACIONES, ASI COMO DE MAGNESIO Y SUS ALEACIONES, SUSTRATOS DE PLACAS CD Y DE ZN. EL COMPLEJO PUEDE PRESENTARSE EN FORMA DE ME SUB 3[CO(NO SUB 2)6] DONDE ME ES UNO O MAS DE NA, K Y LI.(B.) UNA SOLUCION DE CAPA DE CONVERSION QUIMICA PARA PRODUCIR LA CAPA DE CONVERSION DEL COBALTO EN UN SUSTRATO METALICO, LA SOLUCION ES UNA SOLUCION LIQUIDA PROVISTA DE UN PH DE ALREDEDOR DE 7.0 A 7.2 Y QUE CONTIENE UN COMPLEJO HEXACOORDINADO DE COBALTO-III SOLUBLE, LA CONCENTRACION DEL COMPLEJO ES DE ALREDEDOR DE 0.1 MOLECULAS POR GALON DE LA SOLUCION HASTA EL LIMITE DE SATURACION DEL COMPLEJO. LA SOLUCION DE CONVERSION DEL COBALTO PUEDE PREPARARSE MEDIANTE UNA SECUENCIA DE PREPARACION DE BAÑO QUE INCLUYE LOS PASOS DE: (A) DISOLVER UNA SAL DE NITRITO METALICO; (B) DISOLVER UN ACELERADOR TAL COMO NAL; (C) DISOLVER UNA SAL DE COBALTO III; Y (D) AÑADIR DESPUES UN OXIDANTE TAL COMO AGUA. (C.) UN ARTICULO RECUBIERTO QUE EXHIBE PROPIEDADES DE RESISTENCIA A LA CORROSION Y DE ADHESION DE LA PINTURA, EL ARTICULO INCLUYE: (A) UN SUSTRATO METALICO; Y (B) UNA CAPA DE CONVERSION DEL COBALTO FORMADA EN EL SUSTRATO, QUE INCLUYE OXIDO DE ALUMINIO AL SUB 2 O SUB 3, COMO PORCENTAJE MAYOR DE VOLUMEN Y OXIDOS DE COBALTO COO, CO SUB 3 O SUB 4 Y CO SUB 2 O SUB 3.
