Title:
ALKALINE ZINC-IRON PLATING BATH
Document Type and Number:
WIPO Patent Application WO/2021/117882
Kind Code:
A1
Abstract:
This alkaline zinc-iron plating bath contains a zinc compound, an alkali hydroxide, a metal salt including iron, and a complexing agent, the complexing agent being an aliphatic compound comprising five or more hydroxy groups. Due to an inhibitor effect, for example, obtained by employing an aliphatic compound having a chain structure comprising five or more hydroxy groups as the complexing agent, redissolution of a deposited plating film is suppressed, and as a result, it is possible to efficiently form a plating film having a large film thickness.
