  • Zn-Mg alloy plated steel material having excellent corrosion resistance and plating adhesion
    Patent number: 11136651
    Abstract: Provided is a Zn—Mg alloy plated steel material comprising: a base steel material; and first to third Zn—Mg alloy layers sequentially formed on the base steel material, wherein the first to third Zn—Mg alloy layers have a Zn single phase, a Mg single phase, a MgZn2 alloy phase, and a Mg2Zn11 alloy phase, an area rate of the MgZn2 alloy phase included in the first to third Zn—Mg alloy layers is larger than an area rate of the Mg2Zn11 alloy phase included in the first to third Zn—Mg alloy layers, and an area rate of a MgZn2 alloy phase included in each of the first to third Zn—Mg alloy layers is larger than an area rate of a MgZn2 alloy phase included in the second Zn—Mg alloy layer.
