Abstract

Patente de Invenção:<B>"MéTODOS E APARELHO PARA PROTEçãO CATóDICA"<D>. Aparelho, composições e métodos proporcionam proteção catódica a uma estrutura através da colocação de uma camada de ânodo diretamente entre a estrutura e sua fundação circundante. Estruturas consideradas a serem protegidas dessa maneira incluem especialmente estruturas muito grandes, tal como tanques de armazenamento acima do solo. Em um aspecto das concretizações preferidas, a camada de ânodo compreende chapas de pelo menos 85% de alumínio com outros elementos de liga tais como magnésio (0,05 a 6%), zinco (0,1 a 8%), índio (0,005 a 0,03%) e estanho (0,05 a 0,2%) adicionados para fins de otimização do rendimento da corrente, polarização e facilidade de fabricação da chapa. Em outro aspecto das concretizações preferidas, a camada de ânodo compreende pelo menos duas chapas sobrepostas.
