摘要：
The influence of electrochemical treatment in different electrolytes, air oxidation with CuCl2 catalyst and pyrolytic carbon precipitation on surface properties of carbon tissues was studied. At the temperatures up to 130° C activizing treatment of the tissues improves their wettability by pitch at the expense of their surface energy increase. Tissues with another capillary - porous structure (viscose) do not provide similar results for identical exceeding 130° C the activizing treatment does not practically affect tissue wettability by the pitch melt. If coal tar pitch is used as a binder, the required degree of wetting and impregnation of carbon tissues can be attained by isothermal allowance to stand at the temperature ensuring complete wetting (180° C), for instance.
