Title: PLATED STEEL WIRE WITH ZINC ALLOY PLATING LAYER HAVING MULTILAYER STRUCTURE FORMED THEREON, AND METHOD FOR MANUFACTURING SAME
Abstract:
The present invention relates to a method for manufacturing a plated steel wire on which is formed a zinc alloy plating layer having a multilayer structure, the method comprising: a first plating step for galvanizing a steel wire to form a Zn-Fe alloy layer on the steel wire; and a second plating step for zinc alloy plating the galvanized steel wire obtained from the first plating step in a zinc alloy plating bath to form a zinc alloy plating layer. The present invention also relates to a plated steel wire on which is formed a zinc alloy plating layer having a multilayer structure, the plated steel wire being characterized by comprising: a steel wire; and a zinc alloy plating layer plated on the steel wire and having a multilayer structure, wherein the zinc alloy plating layer comprises a first layer including at least one structure among a Zn-Fe structure and a Zn-Fe-Al structure, a second layer including a Zn-Fe-Al structure and at least one structure among a Zn structure, a Zn-Al structure, and a Zn-Al-Mg-Fe structure, and a third layer including at least three among a Zn structure, a Zn-Al-Mg structure, an Mg-Zn structure, and a Zn-Al structure.
