ABSTRACT:
In accordance with the proposed method of making antifriction products, a porous carbon blank is heated up to 1,800.degree. to 2,200.degree. C. and impregnated with molten silicon. The impregnation starts at a temperature of 2,100.degree. to 2,200.degree. C. for 3 to 5 minutes, then at 1,800.degree. to 2,050.degree. C. for 30 to 40 minutes. Thereafter, the blank is cooled down to a temperature of 900.degree. to 800.degree. C. at a rate of 30.degree. to 40.degree. C./min, then down to 200.degree. to 150.degree. C. at a rate of 50.degree. to 100.degree. C./min. This permits obtaining products with an even phase distribution, whereby their wear resistance and strength are improved.
