    摘要: An object of this invention is to provide a copper-tin alloy plating bath that allows for film thickening without using cyanide ions, and that can also be applied to barrel plating. This invention relates to a copper-tin alloy plating bath comprising an aqueous solution containing a water-soluble copper compound, a water-soluble divalent tin compound, a sulfur-containing compound represented by formula (1):

            R-(CH 2 ) 1 -S-(CH 2 ) m -S-(CH 2 ) n -R     (1),

    wherein R is H, OH, or SO 3 Na, and 1, m, and n are each independently an integer of 0 to 3,
    and a hydroxyl group-containing aromatic compound.

    摘要: An object of the present invention is to provide a multilayer plating film with excellent corrosion resistance. The present invention provides a multilayer plating film containing at least a chrome plating film and a tin-nickel plating film, the chrome plating film being the outermost layer, and the tin-nickel plating film being formed below the chrome plating film by using an acidic tin-nickel alloy plating solution containing a divalent tin compound, a nickel compound, a triamine compound, and a fluoride.
