Abstract
A steel wire is coated with a ternary alloy of iron, zinc and aluminum on an outermost surface thereof. The ternary alloy contains 10 to 30 weight percent of aluminum. The steel wire is primarily used as material for springs. An Fe--Zn--Al ternary alloy coated steel wire production method includes immersing a steel wire in a zinc molten bath to plate the steel wire with zinc; immersing the zinc-plated steel wire in a zinc-aluminum molten bath to form a ternary alloy of iron, zinc, and aluminum on a surface of the steel wire; and removing an unsolidified zinc-aluminum layer depositing on an outer surface of the steel wire while being taken out of the zinc-aluminum molten bath to expose the ternary alloy on an outermost surface of the steel wire.
