摘要： A composition and method for deoxidation or "activation" treatment of aluminum according to the stannate process in an alkaline tin solution, for either immersion or electrolytic plating of aluminum with tin, that provides an adherent tin layer and extends the allocable elapsed transfer time, between the activation bath and bronze strike bath, from the 20 seconds of the prior art to up to 2 minutes or more, whereby the stannate method for depositing tin on heavy parts such as aluminum automobile bumpers is commercially practicable for automatic plating of certain aluminum alloys such as alloy 7029.
