Abstract

The results of investigations of the anodic processes of electrodeposition of nickel, nickel-boron alloy, composite coatings nickel-ultrafine diamond and nickel-cobalt-aluminum oxide are presented. It was shown that the oxidation of the boron-containing additive occurs at potentials much more positive than the oxidation potential of nickel, which means that oxidation of the boron compound is impossible under real conditions of electrodeposition. During the electrodeposition of CEC, the anode process proceeds without any complications and the dissolution of the anodes occurs in the same way as in nickel-plating electrolytes, and the composite additives of UDD and Al2O3 do not affect the anodic processes.
