摘要： [Object] To provide a quasicrystal-containing plated steel sheet having a good balance between corrosion resistance and chipping resistance and a method for producing the quasicrystal-containing plated steel sheet.
[Solution] Provided is a quasicrystal-containing plated steel sheet including: a plating layer positioned on at least one surface of a steel sheet; and an alloy layer positioned at an interface between the plating layer and the steel sheet and composed of an Al-Fe intermetallic compound. A chemical composition of the plating layer contains at least, in atom%, Zn: 28.5% to 50%, Al: 0.3% to 12%, and the balance: Mg and impurities, and the plating layer includes, in order from the steel sheet side, a first plating layer which is composed of a structure containing an MgZn phase, an Mg phase, and a quasicrystal phase, and a second plating layer which is positioned on the first plating layer and is composed of a structure containing an Mg 51 Zn 20 phase, a Zn phase, and a quasicrystal phase.
