SHERINE, H.B.; RAJAKUMARI, C.C.  and  RAJENDRAN, S.. Corrosion Behaviour of Stainless Steel 304 Electroplated with Zinc Followed by Blue Passivation. Port. Electrochim. Acta [online]. 2011, vol.29, n.4, pp.295-305. ISSN 0872-1904.

The corrosion resistance of three stainless steel materials, namely, stainless steel (SS), stainless steel electroplated with zinc (SS-Zn) and stainless steel electroplated with zinc followed by blue passivation (BP), has been evaluated in an aqueous solution containing 3.5% NaCl. A potentiodynamic polarization study and AC impedance spectra have been used to investigate the corrosion behaviour of these metals. The corrosion resistance of these materials in 3.5% NaCl increased in the following order: SS>SS+Zn+BP>SS+Zn.

Keywords : decolourisation; corrosion prevention; electroplating; blue passivation.
