- Аннотация: The Ti5Si3Сх-based composites containing 10 vol % Ti2AlC, which are prepared by mechanical alloying of Ti, Si, and Al powders in a liquid hydrocarbon and subsequent heat treatment, are studied. The carbosilicide phase is found to form based on a silicide already at the mechanical alloying stage, whereas Ti2AlC forms during subsequent heat treatment. It is shown that, at 1300°С, the sintering of a sample takes place, which results in the formation of a porous (~13%) composite with a density of 3.75 ± 0.01 g/cm3 and a hardness of 10 ± 1 GPa. The dry friction coefficient of the composite, which is determined upon frictional tests with the WC/6Co alloy counterbody, is ~0.55
