Current-Carrying Wear Behavior of the Laser-Alloyed Al/W Composite Layer Under Different Currents.

Correspondingly, the wear rate exhibited a minimum value of 3.9 × 10 −4 mm 3 N −1 m −1 at 0 A and showed a trend of an initial increase, followed by a decrease, before rising again at higher current levels ( Figure 4 c).

Therefore, as the test current increased from 20 A to 60 A, the friction coefficient and wear rate of the aluminum alloy substrate showed a decreasing trend.
