Abstract: | The current-voltage characteristic, wear resistance, and friction surface roughness of baked model copper-graphite-ShKh15
steel composites are determined. It is shown that the composites containing under 10% and above 50% Cu produce a friction
zone with low conductivity and wear resistance. The composites containing 15–20% Cu produce a friction zone with relatively
high conductivity and wear resistance. The maximum parameters of the roughness (R
a
= 2.98 μm and R
z
= 24.5 μm) appear on the friction surface of the material containing 50% Cu. |
