| 摘要 |
Bright electrodeposits of zinc/iron alloys onto iron of good ductility and adhesion are obtained at low electroplating voltage and high current yield by using a bath containing zinc sulfate, ferrous sulfate, conductive salt, citric acid and alkali metal acetate and, as additional ingredients, saccharin, a naphthalene mono-, -di- or -trisulfonate or a condensation product thereof with formaldehyde and/or an organic complexing agent for iron and further one or more compounds selected from the group consisting of alkali metal cumene sulfonate, alkali metal benzoate, collagen hydrolyzate having a mean molecular weight of from 500 to 2000 and a reducing agent for ferric irons selected from the group consisting of alkali metal bisulfite, alkali metal dithionite and hydroxy ammonium chloride.
