The problem of hydrogen permeation into the boron doped electrodeposited nickel films

This work aim was the researching on the hydrogen penetration into the Ni and Ni-B coatings and on the electrodeposition regimes correlation. The investigations were carried out in the sulfamate nickelling electrolyte with the polyhedral borates class dope. The pH, cathodic current density, electrolyte temperature and alloy boron concentration effects on the hydrogen consumption were studied. The experimental data analysis represented the lower hydrogen consumption in the Ni - B alloy, than in the Ni coating at the same electrolysis regimes.
