摘要： A metallic material is electroplated with an iron-zinc alloy with an improved efficiency by using an electroplating liquid containing, in addition to necessary amounts of zinc and ferrous ions, 0.01 to 10 g/l of an additive consisting of at least one member selected from oxyalkylene compounds of the formulae (I) to (VIII),
wherein
n, n 1 or n 5 = 1 to 200, n 2 or n 6 = 6 to 2000, n 3 or n 7 = 4 to 2000, n 4 = 3 to 2000, R or R 3 = alkyl (C 1 - C 20 ) R 1 , R 2 , R 4 or R 5 = H or alkyl (C 1 - C 20 ) and sulfation products of the above-mentioned compounds.
