Abstract <p>The structure, mechanical and tribological properties determined by it of sintered Al–20 vol % Sn (Al–40 wt% Sn) composites hardened by dispersed hard particles of various types were studied in the work. While maintaining the volume fraction of tin, particles of B₄C, SiC, Al₃Ti, and Al₃Fe with a volume fraction of about 20% were added to the alloy as a strengthening phase. The mixtures were sintered at temperatures below (620°C) and above (710°C) the melting point of aluminum. In order to eliminate residual pores, the sintered samples were subjected to subsequent compaction in a closed die at a temperature of 250°C and a pressure of about 300 MPa. Tribological tests of sintered composites were carried out under dry friction according to the “pin-on-disk” scheme against a steel counterbody. It was found that many of the initial boundaries of iron and titanium aluminides with aluminum grains were preserved during the sintering process, while the carbide particles were completely separated from the aluminum matrix by thin tin interlayers. It was established that the strength of composites with aluminides was higher, and the ductility was lower than that of composites with ceramic particles, regardless of the sintering temperature. It was found that an increase in the sintering temperature has virtually no effect on the wear resistance of hybrid composites during dry friction, with the exception of a composite reinforced with iron aluminides, the wear resistance of which increases by approximately 20%. With increasing pressure, the wear rate of sintered composites during dry friction against steel increases, so it is not recommended to use these materials as antifriction ones at pressures above 3 MPa.</p>
