    摘要: A method for producing zinc coated steel sheet comprises the steps of: forming a Ni--P alloy coating layer containing P of 8 to 15 wt. % on at least one surface of a steel sheet; heat-treating the steel sheet coated with the alloy layer in a non-oxidizing atmosphere to form an Fe--Ni--P diffused alloy layer at an interface of the steel sheet and the alloy coating layer; and zinc coating the steel sheet coated with the diffused alloy layer to form a zinc coating layer.

    摘要: A hot-dip Zn—Al alloy coated steel sheet exhibiting a beautiful coating appearance with metallic luster, in which no spangle or very fine spangles are formed, and having excellent blackening resistance and a method for manufacturing the hot-dip Zn—Al alloy coated steel sheet are provided. The hot-dip Zn—Al alloy coated steel sheet includes a hot-dip Zn—Al alloy coating layer containing 1.0 to 10 percent by mass of Al, 0.2 to 1.0 percent by mass of Mg, 0.005 to 0.1 percent by mass of Ni, and the balance being Zn and incidental impurities on at least one surface of a steel sheet. The manufacturing method includes the steps of dipping the steel sheet into a hot-dip Zn—Al alloy coating bath and pulling up and cooling the steel sheet, wherein the steel sheet pulled up from the coating bath is cooled to 250° C. at a cooling rate of 1° C. to 15° C./sec.
