The mechanical characteristics of high-entropy alloys and their constituent metals were examined by dry friction against diamond at low sliding velocities in air. The friction tests were performed at a velocity of 16 mm/sec and a diamond load of 2.2 N. With increasing friction coefficient, the wear rate of the metals and alloys tends to become higher. The linear wear ranges from 1.06 · 10–7 for chromium to 12.76 · 10–7 for aluminum. In addition, the linear wear of multicomponent alloys is lower than that of their constituent metals and ranges from 0.35 · 10–7 to 4.38 · 10–7. The linear wear of high-entropy alloys is a half to a quarter of the linear wear of individual metals because they differ in hardness, the friction coefficients being equal.
