Title:
PREPARATION OF HIGHLY CORROSION RESISTANT ZINC PLATED MATERIAL
Document Type and Number:
Japanese Patent JPS59173253
Kind Code:
A
Abstract:
PURPOSE: To obtain a highly corrosion resistant Zn-plated material, by applying predetermined plating containing Zn and Al to the outer periphery of a ferrous long material.
CONSTITUTION: Primary Zn-plating is applied to the surface of a long material comprising iron, steel or an iron alloy. Flux based on NH4Cl is applied to the surface of this Zn-plated long material and the coated material is continuously immersed in a Zn-2.5W7% Al alloy bath having a temp. of 410°C or less to be subjected to secondary melt-plating. By this method, a Zn-Al alloy layer rich in brine resistance is applied to the surface of the long ferrous material to obtain a highly corrosion resistant Zn-plated material.
