Tacken, R.A. 't Mannetje, H.H. TNO Industrie en Techniek Publication year 2008 Abstract Nanocrystalline white-bronze, CuSn, electroplating was investigated as alternative to Ni plating as undercoat for noble metals in jewellery applications. A strongly acidic plating bath was developed with an organic additive to suppress hydrogen evolution and obtain bright coatings. Polarization curves indicate a strong inhibition by the organic additive at the tin equilibrium potential. Mass transfer controlled deposition yields nanocrystalline bronze coating with 0-65 wt% Sn. One or two low temperature equilibrium phases, high temperature equilibrium phases or a non-equilibrium phase were identified by XRD analyses. Bright white bronze, 50 wt% Cu/50 wt% Sn, bronze coatings show improved tarnishing resistance and similar corrosion and wear resistance as undercoat for gold on actual jewellery parts compared to nickel. © 2008 WILEY-VCH Verlag GmbH & Co.
