Abstract
Kinetics of electroreduction of Cr3+ ions in an electrolyte based on Cr3+ s
ulfate, which permits to produce thick (up to 100 mum) hard metal layers, i
s studied. The chemical stage of rearrangement of Cr2+ complexes in the nea
r-electrode layer is the reaction's slow stage. The experimental Tafel slop
e b(taf) = 72 mV, which is close to theoretical value of 60 mV, and the rea
ction orders p(H+) = -1 and p(Cr3+) = 1 are explained.
