Investigation of Corrosion Behavior of Coatings Obtained on Steel by Electrospark Alloying with Manual Vibrator of Increased Frequency

The comparative corrosion resistance in acidic, alkaline, and neutral environments of pure metals (steel, nickel, titanium), and of electrospark-alloyed coverings from nickel and titanium received on steel at high-frequency electrospark alloying is investigated. It is established that the phase structure, roughness, and porosity of the received coverings depend on the material of an electrode and on the modes of coatings deposition affect the corrosion behavior. A positive influence of high-frequency alloying with nickel and titanium on an increase in the corrosion resistance of a steel surface is shown.
