Electrodeposition and corrosion resistance of nanocrystalline white bronze (CuSn) coatings

For jewellery applications electroplated white bronze (CuSn) was investigated as undercoating for noble metal finishes as alternative to nickel. A strongly acidic plating bath was developed with an organic additive to suppress hydrogen evolution and obtain bright coatings. An electrochemical study of the bath shows that the additive strongly...
