Abstract

"MéTODO DE ELETRODEPOSIçãO E PRé-TRATAMENTO DE PEçAS DE TRABALHO DE ALUMìNIO". A invenção refere-se a um método para aplicação de uma camada metálica em pelo menos uma superfície de uma peça de trabalho de liga de alumínio, compreendendo as etapas de pré-tratamento da mencionada superfície e aplicação da camada metálica por eletrodeposição, em que a etapa de pré-tratamento compreende um tratamento não-eletrolítico por imersão da peça de trabalho em uma solução ácida simples, preferivelmente uma solução de ácido sulfúrico, tendo uma temperatura de menos de 100<198>C.
