Abstract

"PROCESSO APERFEIçOADO PARA A FORMAçãO DE UMA PELìCULA óXIDO DE REVESTIMENTO DE CONVERSãO DE COBALTO E SOLUçãO DE REVESTIMENTO DE CONVERSãO QUìMICA". Processo aperfeiçoado que é comercialmente prático para a formação de uma película óxido de revestimento de conversão cobalto que apresenta propriedades de resistência à corrosão e de aderência para a pintura sobre um substrato, onde o substrato é alumínio ou uma liga de alumínio, o processo incluindo as etapas de: (a) proporcionar uma solução de película óxido formadora da conversão cobalto compreendendo uma solução aquosa de reação, não contendo trietanclamina (TEA), preparada através da reação dos seguintes materiais iniciadores: (1) um sal de cobalto II CoX~ 2~ solúvel em água, onde X = C1, Br, NO~ 3~, CN, SCN, 1/3 PO~ 4~, 1/2 SO~ 4~, 1/2 CO~ 3~, formiato, ou acetato; (2) um agente complexante solúvel em água, selecionado a partir do grupo consistindo de'MeNO~ 2~, MeAc, MeFm, NH~ 4~Ac, e NH~ 4~Fm, onde Me é Na, K, ou Li; Ac é acetato; e Fm é formiato; (3) um acelerador selecionado a partir do grupo consistindo de NaClO~ 3~, NaBrO~ 3~, e NaIO~ 3~; (4) água; e (b) contatar o substrato com uma solução aquosa de reação por um período suficiente de tempo para oxidar a superfície do substrato, por meio do que a película óxido de revestimento de conversão cobalto é formada, desse modo conferindo propriedades de resistência à corrosão e de aderência para a pintura ao substrato. Também é revelada uma solução de revestimento de conversão química que é comercialmente prática para a produção de uma película óxido de revestimento de conversão cobalto sobre um substrato de alumínio ou de liga de alumínio, a referida solução compreendendo uma solução aquosa de reação, não contendo trietanolamina (TEA), preparada pela reação dos seguintes materiais iniciadores: (1) um sal de cobalto II CoX~ 2~ solúvel em água, onde X = C1, Br, NO~ 3~, CN, SCN, 1/3 PO~ 4~, 1/2 SO~ 4~, 1/2 CO~ 3~, formiato, ou acetato; (2) um agente complexante solúvel em água, selecionado a, partir do grupo consistindo de MeNO~ 2~, MeAc, MeFm, NH~ 4~Ac, e NH~ 4~FM, onde Me é Na, K, ou Li; Ac é acetato; e Fm é formiato; (3) um acelerador selecionado a partir do grupo consistindo de NaClO~ 3~, NaBrO~ 3~, e NaIO~ 3~; e, (4) água.
