Antifriction composite materials (CMs) based on B83 babbitt alloy containing silicon carbide (SiC) and modified shungite rock (MSR) particles were fabricated by hot pressing. The matrix powder was prepared using a planetary ball mill for processing chips obtained after machining of cast babbitt. The resulting powder was sifted out using a sieve analyzer. Powder mixtures for pressing were prepared by mechanical alloying in a planetary mill for 2 h at a rate of stirring of 300 rpm. Composite semifinished product was obtained by pressing the obtained powder mixtures on an OMA mechanical press (Pmax = 150 kN) at a pressure of 320 ± 5 MPa. Semifinished products were heated in a muffle furnace in a die mold at a temperature up to 300°C, held for 30 min at this temperature, and then pressed. We showed that CMs fabricated by the powder metallurgy technique exhibited enhanced wear resistance at comparable values of the friction coefficient as compared to the same characteristics of a cast alloy. Local elastic moduli of the obtained samples were determined using the laser optoacoustic method based on the measurements of the phase velocities of thermo-optically excited longitudinal and shear ultrasonic waves. We have shown that the B83-based CMs containing MSR (0.5 wt %) and SiC (3 wt %) can be recommended as an alternative to the B83 cast alloy. The composite material with such composition exhibits a higher wear resistance as compared to the cast babbitt. The friction surface of this CM reveals sliding areas and friction grooves that are less distinct as compared with the B83 cast alloy.
