Abstract

Patente de Invenção: <B>"SISTEMA ELETROQUìMICO E PROCESSO PARA DECAPAGEM DE REVESTIMENTOS METáLICOS"<D>. é descrito um processo de decapagem eletroquímica que decapa pelo menos um revestimento metálico de um substrato. Devido à seletividade eletroquímica do processo descrito, a liga mãe é afetada minimamente pelo processo de decapagem eletroquímica. O processo compreende o fornecimento de um eletrólito; a disposição dos artigos revestidos e pelo menos um eletrodo no eletrólito; a aplicação de uma corrente entre o eletrodo e os artigos revestidos, e a remoção do, pelo menos um, revestimento dos artigos revestidos sem modificar a liga mãe. O sistema para o processo de decapagem eletroquímica compreende um eletrólito; uma fonte de corrente contínua; e uma pluralidade de eletrodos dos quais uma corrente contínua possa ser direcionada ao artigo que está sendo decapado. A fonte de corrente contínua é capaz de ser conectada aos artigos revestidos e à pluralidade de eletrodos. O sistema permite a remoção de pelo menos um revestimento da liga mãe.
