Abstract

"PEçAS DE ALUMìNIO ELETROGALVANIZADAS, PROCESSO PARA SUA PRODUçãO E PRODUTO OBTIDO". A invenção provê um processo de pré-tratamento para eletrogalvanizar peças ou tiras de alumínio, no qual a solução de zincagem e modificada para melhorar a adesão do eletrogalvanizado subseq³ente ao substrato. A peça ou tira de alumínio, tal como um boneco de moeda ou tira para bonecos de moedas de alumínio, é pré-tratada com uma solução de zincato melhorada que provê íons hidróxido em uma quantidade na faixa de 75 a 175 g/1, íons zinco em uma quantidade na faixa de 15 a 40 g/1, íons níquel em uma quantidade na faixa de 2 a 10 g/1, e íons cobre em uma quantidade na faixa de 1,5 a 5 g/1. O processo de pré-tratamento preferivelmente inclui uma deposição de cobre aplicada de um banho de deposição de cianeto de cobre a um pH na faixa de 8,5 a 11,0, usando uma densidade de corrente na faixa 0,1 a 10 A/dm^ 2^ . As etapas de pré-tratamento e eletrogalvanização são preferivelmente conduzidas por galvanização em tambor, de acordo com um outro aspecto da invenção. A invenção também provê peças ou tiras de alumínio eletrogalvanizadas, tais como bonecos de moedas eletrogalvanizados, incluindo um substrato formado de alumínio ou uma liga de alumínio e tendo superfícies múltiplas,uma camada de zincato sobre pelo menos uma das superfícies do substrato e preferivelmente envolvendo completamente o substrato, uma camada de deposição de um metal de deposição cobrindo a camada de zincato, e uma ou mais camadas eletrogalvanizadas de um ou mais metais cobrindo a camada de deposição, as ditas uma ou mais camadas eletrogalvanizadas aderindo ao substrato de maneira a suportar um processo de deformação sem a delaminação do substrato.
