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 MgZnalloy phase, and a MgZnalloy phase, an area rate of the MgZnalloy phase included in the first to third Zn—Mg alloy layers is larger than an area rate of the MgZnalloy phase included in the first to third Zn—Mg alloy layers, and an area rate of a MgZnalloy phase included in each of the first to third Zn—Mg alloy layers is larger than an area rate of a MgZnalloy phase included in the second Zn—Mg alloy layer.
