Abstract:
An Mg-containing Zn alloy coated steel including a steel and a metallic coating layer placed on a surface of the steel, in which the metallic coating layer is a layered structure of a flat-form metal particle having a particle diameter of from 5 to 100 μm, and a thickness of from 0.5 to 30 μm, the composition of the metal particles include, in terms of % by mass, Zn from 11 to 80%, Al from 3 to 80%, Mg from 8 to 45%, and Ca from 1 to 5%, while the balance is impurities, and the Zn content, the Al content, and the Mg content in terms of % by mass satisfy Zn+Al>Mg, and in which the metal particles include a quasicrystalline phase, an MgZn 2  phase, and a balance structure, in which the total area fraction of the quasicrystalline phase and the MgZn 2  phase is 45% or more, the area fraction of the balance structure is from 0 to 55%, the area fraction of the quasicrystalline phase is 20% or more, and the area fraction of the MgZn 2  phase is 3% or more.

Claim (Index 5):
The Mg-containing Zn alloy coated steel according to  claim 1 , wherein the composition of the metallic coating layer comprises one or more of, in terms of % by mass: Y at from 0% to 3.5%, La at from 0% to 3.5%, Ce at from 0% to 3.5%, Si at from 0% to 3.5%, Ti at from 0% to 0.5%, Cr at from 0% to 0.5%, Co at from 0% to 0.5%, Ni at from 0% to 0.5%, V at from 0% to 0.5%, Nb at from 0% to 0.5%, Cu at from 0% to 0.5%, Sn at from 0% to 0.5%, Mn at from 0% to 0.2%, Sr at from 0% to 0.5%, Sb at from 0% to 0.5%, Pb at from 0% to 0.5%, C at from 0% to 0.5%, Fe at from 0% to 0.5%, and Cd at from 0% to 0.5%, and satisfies the following Formula (A), and the following Formula (B):\n Formula (A): Ca+Y+La+Ce\u22643.5% Formula (B): Ti+Cr+Co+Ni+V+Nb+Cu+Sn+Mn+Sr+Sb+Pb+C+Fe+Cd\u22640.5%, wherein, in Formula (A) and Formula (B), an element symbol stands for the content of the element in terms of % by mass.
