SEM images of worn surfaces after tribological testing: (a) PN + DLC, showing moderate grooves and adhesive wear features; (b) ZrN + DLC, exhibiting shallower grooves and more uniform wear pattern; (c) TaN + DLC, with minimal surface damage and scattered shallow scratches, indicating superior wear resistance.
