FIELD: electricity.
SUBSTANCE: cathodes have stabilised surface incorporating mixture of carbon material, TiB2 and up to 25 wt % of fine additive being comprised of a mixture from two homogeneously mixed up compositions. The produced mixture is then transferred into the component of electrolytic cell, where the melting point of at least one additive composition is higher than the temperature of electrolytic cell component thermal treatment. If such electrolytic cell component contacts melted aluminium, the latter interacts with the additive and creates dense phase on the surface of electrolytic cell component. The above-mentioned dense phase has low solubility in aluminium.
EFFECT: method ensures simple and cheap prevention of metal borides leaching from carbon-based composite materials blocks.
