The results of wear testing of the SMIC of the copper-aluminum system at the angle of action of the abrasive relative to the metal-intermetallic layers - 0, 45 and 90º are given. It is shown that the wear resistance of SMIC is 3.2 ÷ 3.3 times higher than that of AD1 aluminum. At the same time, the samples showed the best indicators of wear resistance when the abrasive was applied to the layered structure of the tested SMIC at an angle of 45º. Analysis of the wear surfaces obtained by friction in all directions with respect to the layers of the SMIC made it possible to identify all the main morphological types of wear particles in the conglomerate. It is shown that additional saturation of the hard phases (intermetallic or abrasive) with pressed particles of soft metal layers contributes to the implementation of the Charpy principle.
