Abstract

LAS CAPAS DE PALADIO SE UTILIZAN CON FRECUENCIA COMO CAPAS PROTECTORAS SOBRE LA SUPERFICIE DE SUBSTRATOS ELABORADOS DE COBRE, NIQUEL Y COBALTO, ASI COMO SUS ALEACIONES CON UNO O CON OTRO Y/O CON FOSFORO O BORO. LOS PROCESOS CONOCIDOS, SIN EMBARGO, NO PERMITEN CAPAS DE PALADIO ADHESIVO, PERMANENTEMENTE CON BRILLO, ASPECTO CLARO, SIENDO DEPOSITADO CON POCOS POROS. TALES CAPAS DE PALADIO PUEDEN SER SIN EMBARGO DEPOSITADAS MEDIANTE BAÑO QUIMICO LIBRE DE FORMALDEHIDO QUE CONTIENE UNA SAL DE PALADIO, UNO O VARIOS AGENTES DE FORMACION COMPLEJA NITROGENADA Y ACIDO FORMICO O DERIVADOS DE ACIDO FORMICO A UN VALOR DE PH MAYOR DE 4. ES TAMBIEN POSIBLE UN TRATAMIENTO PREVIO EN UN BAÑO DE PALADIO DE CEMENTACION.
