摘要： PURPOSE: To impart excellent press formability and bulging property by controlling the shape and coverage of plating crystal grains to be formed at the time of forming galvanizing layers on an aluminum alloy plate. CONSTITUTION: The crystals of the galvanizing layers are formed in a granular form and the coating area thereof is confined to . The ratio of the height and width of these grains have the form of height/width = 1/20 and the coverage on the surfaces of the aluminum allay plate is specified to 5 to 70% by forming the grain shape of 0.1 to 50μm in the spacings between the respective grains. The coating surfaces of the plating may be on both of the front and rear of the aluminum alloy plate or on one surface and may be preferably on both front and rear in terms of formability. The plating layers are formed by subjecting the aluminum alloy plate to an electrochemical anode treatment with an energization quantity of 1 to 100c/dm , then subjecting the plate to electroplating for a higher effect. Any methods are adoptable for the electrochemical treatment method, insofar as an electrochemical anode reaction is effected on the surfaces of the aluminum alloy plate and the prescribed current quantity is assured by such methods.
