... using a pin-on-disk wear tester. Wear experiments have been conducted under dry sliding conditions at different operating loads (10, 20, 30, and 40 N) and sliding velocities (0.1, 0.2, 0.3, and 0.4 m/s) at room temperature. The incorporation of ZrO 2 nanoparticles improves the microhardness of the cast...

Under higher loads, the oxide layer on the alloy surface fractured, resulting in the generation of flake-like debris, which contributed to third-body abrasion. Additionally, the study examined the transfer film formation on the alumina counterface under...

In simple sliding intermittent motion, the temperature rise plays a crucial role in the variation of the oil film, particularly during the motion phases, and is an unavoidable factor. An increase in stop time reduces the film thickness...
