<p>Disclosed are a hot dip zinc alloy plated steel sheet having a nano-wire on the surface and a method for manufacturing the same. According to an embodiment of the present invention, the method for manufacturing a hot dip zinc alloy plated steel sheet comprises: a step of preparing a hot dip zinc alloy plating bath composed of 1-15 wt% of aluminium, 1-4 wt% of magnesium, remaining amount of zinc, and impurities; a step of manufacturing a hot dip zinc alloy plated steel sheet by immersing a base material steel sheet in the hot dip zinc alloy plating bath; and a step of treating the surface of the hot dip zinc alloy plated steel sheet by irradiating plasma onto the hot dip zinc alloy plated steel sheet, wherein the incidence angle of the plasma is 10-30°.</p> |
