METHOD FOR ELECTROPLATING WITH MAGNESIUM ALLOY A PLATE

The object of the invention is intended to provide the magnesium alloy sheet which successively forms the CuCN, the copper sulphate, the nickel, the trivalency chromium plating layer into the wet electrolytic plating method using the wet electroplating solution in which the plating cost is remarkably low. A method for plating the trivalency chrome(50) comprises a first process of washing the magnesium alloy sheet surface; a second process of removing the foreign material of the magnesium alloy sheet surface; a third process of oxidizing; a fourth process of removing the attach product; a fifth process of making with the zinc substitution; a sixth process of electroplating in the CuCN electrolysis leakage paste; a seventh process electroplating in the copper sulphate electroplating solution; an eighth process of electroplating in the nickel electroplating solution; and a ninth process of electroplating in the trivalent chrome electroplating solution.
