Abstract
PURPOSE: A method for manufacturing zinc-nickel alloy plated steels with superior anti-corrosiveness is provided for the application to automobile bodies and sash that require high corrosion resistance. CONSTITUTION: In a manufacture process of a zinc-nickel alloy plated steel, the plating process of a zinc-nickel alloy is performed by dipping in an electrolytic solution comprising 10-35wt.% of ZnSO4·7H2O, 60-85wt.% of NiCl2·6H2O and 2-10wt.% of (NH4)2Cl2 at a temperature range of 48 to 52deg.C under the conditions of a current density ranging from 200 to 500mA/cm¬2 and a pH ranging from 2 to 2.5. By conducting plating operation on above conditions, a plated layer having a thickness of 10 to 17μm is obtained, and then by using an abrasive that is made of diamond paste, polishing operation is carried out to polish the surface of the zinc-nickel alloy plated steel about 1 to 2μm.
