Fig. 4 Wear kinetics of the composites based on titanium MAX phase and aluminum alloy in
pair with copper (a) and of copper in pair with the composites and aluminum alloy (b). The curve
numbers correspond to the material variant number in Table 1
A more diverse picture is observed by the results of copper wear in contact with the
studied composites (Fig. 4b, Table 2). Composite materials of variants 1–4 obtained
by one-step technology: hot pressing at 30 MPa cause significant wear of copper,
even more (variants 1–3) than aluminum alloy (variant 8). When the hot pressing
pressure decreases from 30 to 15 MPa, sufficiently porous materials (variants 5 and
