Abstract (en)
[origin: EP0632140A1] A method for producing zinc coated steel sheet comprises the steps of: forming a Ni-P alloy coating layer containing P of 8 to 15wt.% 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.
