Abstract
"PROCESSO E APARELHO PARA REMOVER UMA PELìCULA DERIVADA DE Ti" Uma solução aquosa (20) de um hidróxido alcalino é armazenada e contida em um tanque (1). Um eletrodo (5) está disposto no tanque (1) e um membro (11) revestido com uma película derivada de Ti está disposto no tanque (1) de modo a ser circundado com o eletrodo (5). Nesta condição, uma fonte de energia (6) aplica um potencial negativo ao eletrodo (5) e um potencial positivo ao membro (11) para fluir eletricidade entre o eletrodo (5) e o membro (11) imerso na solução (20). Assim, a película derivada de Ti revestida na superfície do membro (11) é quimicamente removida pela solução aquosa (20).
