Abstract / Full Text

The corrosion current density of Ni–Re alloy (15.8 wt % Re) was estimated using recently developed method of compensating additives. The alloy was fabricated by the electrodeposition in the form of bulk specimen and the powder prepared of this specimen. The electrodeposition was performed in stirred 5 × 10–3 M HCl solution. The method enabled us to determine the corrosion rate with no external polarization of studied specimens and at virtually constant pH value. A specific electrochemical activity of powder surface was estimated by comparing the corrosion currents of bulk and powder specimens. The powder was intended for testing its catalytic activity in several electrochemical reactions.
