The MC-SPG-based approach is used to study how plastic deformation, thermal response, and wear are influenced by the variation of the vertical overlap between colliding spherical asperities. The findings demonstrate a critical overlap value where the wear mechanism transitions from plastic...

... influencing parameter on WR, followed by MT, D, and V. The optimal values of influencing parameters for WR are as follows: MT = T2, L = 10 N, V = 2 m/s, and D = 500 m. The wear mechanisms at the highest and lowest WR conditions were also studied by observing their scanning electron micrographs (SEM) on wear...

A series of friction and wear tests were carried out, and wear topography and friction vibration were measured. With the increase of electric current, the wear mechanism of CG30...

... on drilling in the deep space environment. The results prove that the coefficient of friction (CoF) is interrelated with load and wear conditions, where CoFs gradually decrease with load growth in both air and vacuum. When the loads keep increasing, however, the wear mechanisms finally change under the high...
