Abstract

The features of the structure formation of Al-Cu and Al-Cu-C materials under conditions of spark-plasma sintering under conditions of superposition of a direct and pulsating current at a temperature of 600ºC and a mechanical pressure of 60 MPa are studied. The obtained Al-Cu-C system materials with hardness from 400 to 1000 MPa, porosity from 3 to 1% are recommended for use as slip contacts, and also as antifriction materials in friction pairs either in dry (carbon-containing composites) or wet friction (composites not containing carbon).
