Abstract
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 Ga 36 Ni 64 (Ga Ni 2 ) compound and gallium with copper form CuGa 2 compound. Different acids were used for electrode leaching: H 2 SO 4 ; HNO 3 ; H 3 PO 4 ; HCI. It was shown that only hydrochloric acid is suit-able for gallium plating of the electrodes.
