Abstract—Electrochemical and corrosion properties of nickel in neutral, alkaline, and acidic solutions are
studied. Chemical and phase composition of surface films and surface morphology are examined. The effect of
electrolyte composition and concentration on the metal removal rate in the course of broaching is determined.
Optical, electrochemical, and gravimetrical methods, x-ray diffraction analysis, and thermogravimetry were
used in the work.
