Conditions of gallium plating of metal electrodes were studied in the paper. It was found that stability of gallium cover depends on the material and is increasing in the raw: stainless steel 08Х18Н12Т < Steel 1, Steel 2, Steel 3, Steel 45 < Ni < Cd < Cu. Phase composition of the electrode surface layer obtained after gallium plating was studied. It was found that gallium with nickel form Ga₃₆Ni₆₄(Ga Ni₂) compound and gallium with copper form CuGa₂compound. Different acids were used for electrode leaching: H₂SO₄; HNO₃; H₃PO₄; HCI. It was shown that only hydrochloric acid is suit-able for gallium plating of the electrodes.
