Abstract
Provided are a single layer zinc alloy plated steel material and a fabrication method therefor, the single layer zinc alloy plated steel material comprising a base iron and a zinc alloy plating layer formed on the base iron, wherein the zinc alloy plating layer contains 13-24 wt % of Mg, and the adhesion amount of the zinc alloy plating layer is at most 40 g/m2 (excluding 0 g/m2).
Claims14
A single layer zinc alloy plated steel comprising:
- a base steel and a zinc alloy plating layer disposed on the base steel,
- wherein the zinc alloy plating layer includes 13 to 24 wt % of magnesium (Mg), and a plating amount of the zinc alloy plating layer is 40 g/m2 or less (excluding 0 g/m2).
A method of manufacturing a single layer zinc alloy plated steel material, comprising:
- preparing a base steel;
- and
- levitating and heating a coating material by electromagnetic force in a vacuum chamber to generate zinc (Zn) and magnesium (Mg) alloy deposition vapor, and inducing and spraying the Zn and Mg alloy deposition vapor onto a surface of the base steel to form a Mg deposition layer,
- wherein a content of Mg in the Zn and Mg alloy deposition vapor is 13 to 24 wt %, and a plating amount of a zinc alloy plating layer is 40 g/m2 or less (excluding 0 g/m2).
