MAGNETOOPTICAL STUDIES OF THE PROCESSES OCCURRING AT THE SURFACES OF NI, LANI5, AND TIFE ELECTRODES IN THE COURSE OF THEIR ELECTROCHEMICAL TREATMENT IN KOH AND H2SO4

The measurements of the equatorial Kerr effect showed that cathodic tr eatment of nickel electrodeposits in KOH results in die leveling of th e electrodeposit relief. Cathodic treatment of the nickel deposits in H2SO4 at high current densities gives rise to the grain orientation of the deposits. The formation of metallic nickel and iron was detected at the surfaces of LaNi5 and TiFe0.85Zr0.12Mo0.03 alloys after the cyc les of their potentiostatic oxidation-reduction in KOH.
