FIELD: metallurgy.
SUBSTANCE: at first surface of nickel containing material is degreased, further it is treated approximately for 10 minutes to make surface rough in approximately 1% solution of hydrochloric acid; also process is accelerated with addition of hydrogen peroxide. Surface of nickel containing material is washed, then this material is inserted into 3.5 molar solution of caustic alkali mixed with approximately 10% hydrogen peroxide and maintained there approximately for 10 minutes. In the following thermal process surface of nickel hydroxide thereby obtained is dehydrated and oxidised to nickel oxide. The invention also refers to electro-conducting surface layer thus obtained, also to electrodes produced out of it, to their application in the process of chlorine-alkaline electrolysis and in fuel elements and accumulators.
EFFECT: facilitating extremely high electro-conductivity of nickel oxide surface layers.
