Abstract

(A.) UN PROCESO PARA LA FORMACION DE UN RECUBRIMIENTO DE CONVERSION DE COBALTO EN UN SUBSTRATO DE METAL, IMPARTIENDO, DE ESTE MODO, PROPIEDADES DE RESISTENCIA A LA CORROSION Y ADHERENCIA DE LA PINTURA. LA INVENCION SE REALIZO COMO SUBSTITUYENTE DEL PROCESO DE ACIDO CROMICO DE DISEÑO PREVIO. EL PROCESO INCLUYE LOS PASOS DE: (A) SUMINISTRO DE UNA SOLUCION DE CONVERSION DE COBALTO QUE COMPRENDE UNA SOLUCION ACUOSA QUE CONTIENE UN COMPLEJO HEXAVALENTE DE COBALTO-III SOLUBLE, SIENDO LA CONCENTRACION DEL COMPLEJO HEXAVALENTE DE COBALTO-III SOLUBLE DE 0,01 MOLES, APROXIMADAMENTE, POR LITRO DE SOLUCION HASTA EL LIMITE DE SATURACION DEL COMPLEJO HEXAVALENTE DE COBALTO-III SOLUBLE Y ACIDO ACETICO; Y (B) PUESTA EN CONTACTO DEL SUBSTRATO CON LA SOLUCION DURANTE UN PERIODO SUFICIENTE DE TIEMPO, DE ESTE MODO SE FORMA EL RECUBRIMIENTO DE CONVERSION DE COBALTO. EL SUBSTRATO PUEDE SER ALUMINIO O ALEACION DE ALUMINIO, ASI COMO REVESTIDO DE CD, REVESTIDO DE ZN, REVESTIDO DE ZN-NI Y ACERO. EL COMPLEJO HEXAVALENTE DE COBALTO-III SOLUBLE PUEDE ESTAR PRESENTE EN FORMA DE [CO(NH3)6]X3 EN DONDE X ES CL, BR, NO3, CN, SCN, PO4, SO4, C2H3O2 O CO3. (B.) UNA SOLUCION DE RECUBRIMIENTO DE CONVERSION QUIMICA PARA PRODUCIR EL RECUBRIMIENTO DE CONVERSION DE COBALTO, INCLUYENDO LA SOLUCION UNA SOLUCION ACUOSA QUE CONTIENE UN COMPLEJO HEXAVALENTE DE COBALTO-III SOLUBLE, SIENDO LA CONCENTRACION DEL COMPLEJO HEXAVALENTE DE COBALTO-III SOLUBLE DE 0,01 MOLES, APROXIMADAMENTE, POR LITRO DE SOLUCION HASTA EL LIMITE DE SATURACION DEL COMPLEJO HEXAVALENTE DE COBALTO-III. LA SOLUCION DE CONVERSION DE COBALTO SE PUEDE PREPARAR MEDIANTE UNA SECUENCIA DE COMPOSICION DE BAÑO QUE INCLUYA LOS PASOS DE: (A) DISOLUCION DE UNA SAL DE COBALTO-II; (B) A CONTINUACION, DISOLUCION DE UNA SAL DE NITRATO METALICO; Y (C), A CONTINUACION, LA ADICION DE ACETATO DE AMONIO. (C.) UN ARTICULO RECUBIERTO QUE MUESTRA PROPIEDADES DE RESISTENCIA A LA CORROSION Y ADHERENCIA DE LA PINTURA, INCLUYENDO EL ARTICULO: (A) UN SUBSTRATO METALICO; Y (B) UNRECUBRIMIENTO DE CONVERSION DE COBALTO FORMADO EN EL SUBSTRATO, INCLUYENDO EL RECUBRIMIENTO DE CONVERSION DE COBALTO OXIDO DE ALUMINIO AL2O3 COMO PORCENTAJE MAYOR DE VOLUMEN Y OXIDOS DE COBALTO COO, CO3O4 Y CO2O3.
