Abstract
PURPOSE: To enable to be obtained and above mentioned alloy excellent in anticorrosive property, by containing each salt of pyrophosphoric acid alkali metal, Sn(II) and Ni as main component and adding a limited quantity of sulfur contained amino acid (salt) to plating solution contained a specific quantity of Sn snd Ni.
CONSTITUTION: The following compounds are added to plating solution containing pyrophosphoric acid alkali metal salt, Sn (II) salt (for example; SnCl2) and Ni salt (for example; NiCl2) as main component and also containing Sn:1W15g/l, Ni: 5W50g/l calculated in terms of metal and moreover, making [Ni/(Ni+Sn)]× 100 at 60W95. That is, suflur-contained amino acid (slat), for example, 0.1W 30g/l (preferably 1W10g/l) of methionine, is added. Or, moreover, oxyacid (salt), for example; 10W200g/l of ammonium citrate or 5W100g/l of amine compound (ethylene diamine), is added. By the above additional addition, stability of plating solution is improved and current density extent obtaining black luster plating, is enlarged.
