Abstract

PURPOSE: To form a layer plated with Fe-Zn alloy which is excellent in coating finishing properties, film homogeneity and appearance properties, etc., by adding a specified pH buffering agent and a nonionic surfactant into a sulfate-base Fe-Zn alloy plating bath and performing electroplating while moving the plating bath relatively to the material to be plated.
CONSTITUTION: One or more kinds of citric acid, malonic acid, oxalic acid, acetic acid, tartaric acid or salts thereof are added at 10W500g/l total amount as a pH buffering agent to an Fe-Zn alloy electroplating bath in which Fe ion and Zn ion are dissolved in a sulfate form and one or more kinds of polyethylene glycol and polypropylene glycol or their derivatives having 100W10,000mol. wt. are added at the rate of 0.1W10ppm as a nonionic surfactant to the electroplating bath. While this plating bath is allowed to flow at the relative flow velocity not less than 0.5m/sec to the material to be plated, electroplating is performed.
