... coefficient decreases with the increase of current density when the current density is less than 10A/mm 2 , and the wear mechanism is mainly abrasive wear. When the current density is greater than 10A/mm 2 , the friction coefficient increases with the increase of current density, and the wear mechanism...

... from 0% to 8%. Tests conducted using pin-on-disc equipment under various conditions, including loads of 5–15 N, sliding velocities of 0.5–1.5 m/s, sliding distances of 80–120 m, and abrasive grit sizes of 80–150 µm, revealed significant findings. The Al–6TiC nanocomposite demonstrated an 18% reduction...

... that at the lowest load, 0.2 N, where the wear resistance of the implanted NiTi is much higher than that of non-implanted NiTi, there is a difference in wear mechanisms. In implanted NiTi, the regular form of wear scar in the initial stage of wear indicates a moderate abrasive wear, while in longer wear tests...
