PURPOSE: A surface treatment method for magnesium alloy parts is provided to improve corrosion resistance of the magnesium alloy parts by forming a dense coating layer within a short time. CONSTITUTION: A surface treatment method for magnesium alloy part is as follows. Oil is removed from the part surface(10). Scratch is removed from the part surface(20). The part is charged into a coil in which AC current of high frequency flows, and heated through electromagnetic induction(30). The heated part and a reference conductor are connected to an anode and a cathode and dipped in electrolyte so that an oxide coating film is formed on the parts surface(40).
