Beschreibung
Zusammenfassung:	This zinc-nickel composite plating bath contains a zinc source, a nickel source, silicon dioxide particles and an ammonium-based dispersant in such ranges that enable the achievement of a zinc-nickel composite plating film wherein the codeposition amount of nickel is 10-16 wt % and the codeposition amount of the silicon dioxide particles is 7 vol % or more. Meanwhile, the pH of this zinc-nickel composite plating bath is 5.6 to 6.8.
