Abstract

Abstract

The brightener CT-2 was shown to be a strong inhibitor to the deposition of zinc, increasing cathodic polarization by about 100 mV, decreasing the cathodic peak current by about 20 times, and also to be a very strong promoter of nucleation, increasing the nucleus number density by 2 orders of magnitude, so that it would be reasonable to get quality electroplates with fine grains, bright and smooth surface and very few defects by using the brightener.
