The electrochemical behavior of tin, copper and nickel ions was studied by cyclic voltammetry. The experimental results show that when tin, copper and nickel ions coexist in the electrolyte solution and the AC power is used as the electrolysis source, tin, copper Will be deposited on the surface of the aluminum in preference to nickel to form a bright black solid film, electrodeposition 10 min, film thickness greater than 4μm. The surface morphology of the film was analyzed by scanning electron microscopy. The composition of the film and the relative contents of tin and copper in the film were analyzed by X-ray photoelectron spectroscopy
