Kinetics of step-wise discharge of Cr(III) to Cr(0) in electrolytes containing aminoacetic acid is studied. The limiting current of Cr(II) ion discharge to metal is much lower than the limiting diffusion current of Cr(III) reduction to Cr(II), which results in the accumulation of Cr(II) ions in the electrolyte even at the potentials of the limiting current of chromium electroplating. The apparent catalytic effect of OH–ions during Cr(II) discharge is associated with the formation of electroactive hydroxocomplexes of bivalent chromium. The kinetic equation of the studied process is derived and analyzed. The probable nature of the limiting currents of chromium electroplating is discussed.
