PCT No. PCT/SU80/00101 Sec. 371 Date Jan. 26, 1982 Sec. 102(e) Date Jan. 26, 1982 PCT Filed Jun. 9, 1980 PCT Pub. No. WO81/03452 PCT Pub. Date Dec. 10, 1981.A process for producing antifriction materials comprising heat-treatment of a carbonaceous base-a siliconized graphite consisting of 5 to 25% by weight of silicon, 25 to 55% by weight of silicon carbide, carbon being the balance, in a vacuum of fron 10-1 to 10-3 mm Hg at a temperature within the range of from 1,500 DEG to 2,000 DEG C. for a period of from 15 to 60 minutes, followed by impregnation of the carbonaceous base with metals or alloys thereof.
