Paper Title:
Effect of Ni2+ on Chromium Electrodeposition in Cr(III) Plating Bath
  Abstract

A small amount of nickel ions is added to trivalent chromium chloride plating bath to study effect of Ni ions on trivalent chromium electrodeposition. The obtained Cr-Ni alloy coatings and Cr coatings are characterized by means of EDS and SEM. Cathodic polarization curves of trivalent chromium chloride plating bath show that right amount of Ni ions contained in bath make the LSV more positive, exerting a catalytic effect on electrodeposition of Cr ( ) ions. EDS results of the obtained coatings also demonstrate the catalytic effect of Ni ions on trivalent chromium electrodeposition. Analysis of SEM indicate that the surface morphology of coatings obtained from Cr( ) bath containing 0.03g/L Ni2+ bath are similar to the ones obtained from pure Cr( ) ions bath.
