We study the tribological properties of materials used as electrocontact inserts of the tram pantographs in couples with M1copper of the contact wires of power electric circuits. As promising materials for the pantograph insert, we considered the composites based on the MAX phases of Ti3AlC2, (Ti, Nb)3AlC2, and Ti2AlC and also on TiC and Al2O3. The highest wear resistance was detected for composites...
