摘要
PURPOSE: A surface processing method for enhancing the corrosion-resistance of a galvanized sheet is provided to increase corrosion resistance and to prevent the decrease of shaping performance since the etching of a layer can be limited.;CONSTITUTION: A surface processing method for enhancing the corrosion-resistance of a galvanized sheet comprises next steps. Zinc is plated on a steel sheet to form a zinc-plating steel sheet. One of washing, pickling and degreasing processes is made on the zinc-plating steel sheet to be washed. The washed zinc-plating steel sheet is mounted on the susceptor in a plasma reactor. Gas is injected into the plasma reactor to form plasma. The zinc-plating steel sheet is exposed to the plasma and the surface of the zinc-plating steel sheet is processed using the plasma.;COPYRIGHT KIPO 2011
