The advantages of aluminum alloy airport seating plating process 1, the surface of aluminum and aluminum alloy directly lead plating process without zinc immersion, pre-plated copper, pre-plated nickel, coated conductive layer and other complex pre- treatment. It is only a few simple chemical and electrochemical treatment.It will be able to d irectly on the substrate lead, and the operation is simple, low cost, easy to achieve industrial production. 2.The lead coating prepared by this method is smooth, uniform, dense and free of bubbles. It has good adhesion with lead base, and is proved to be suitable for the preparation of light grid and anode material for lead acid battery.
