Sliding contact creates universal self-affine fractal surfaces
Ruibin Xu, Haohao Ren, Adriane Clerc +4
Surface roughness evolves during sliding, a process known as run-in, and the resulting topography controls friction, leakage, and failure from machines to geological faults. Yet th…

Brownian friction dynamics: fluctuations in sliding distance
Ruibin Xu, Feng Zhou, B. N. J. Persson
We have studied the fluctuation (noise) in the position of sliding blocks under constant driving forces on different substrate surfaces. The experimental data are complemented by s…
