Abstract

"COMPOSIçãO PARA REMOVER MANCHAS DE ATAQUE QUìMICO DE UMA SUPERFìCIE DE ALUMìNIO". Esta invenção provê uma composição e processo melhorados para o pré-tratamento de alumínio antes da eletrodeposição. A invenção é uma composição aquosa composta de um ácido, um agente oxidante, e opcionalmente um composto halogenado. Esta composição é utilizável em um processo que efetivamente remove as manchas que resultam da etapa de ataque químico do processo de pré-tratamento de alumínio. Alternativamente, a composição pode ser usada em um processo que combina as etapas de ataque químico e de remoção das manchas do ataque químico em pré-tratamento de A1.
