Abstract

PURPOSE: To enable to be obtained the above mentioned alloy excellent in anticorrosive property and discoloration resisting property, by containing Sn(II) salt, Ni salt and tripolyphosphoric acid alkali metal salt as main component and also adding a limited amount of sulfur-contained amino acid (salt) to plating solution containing a specific amount of Sn and Ni.
CONSTITUTION: The following compounds are added to plating solution containing Sn(II) salt (for example; SnCl2), Ni salt (for example; NiCl2) and tripoliphosphoric acid alkali metal salt as main component and also, containing 2W25g/l of Sn and 2W50g/l of Ni calculated in terms of metal. That is, 0.1W30g/l, preferably 1W 10g, of sulfur-contained amino acid (salt) is added. Or, moreover, 10W200g/l of oxyacid (salt) (for example; ammonium citrate) or 5W100g/l of amine compound (for exampe; ethylenediamine) is added. By the above additional addition stability of plating solution is improved and at the same time, black luster is obtained throughout a wide extent current density.
