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…

Adhesion-controlled sliding and the Stribeck curve in hydrophobic soft contacts
Ruibin Xu, Charlotte Spies, Michele Scaraggi +1
We present an experimental and theoretical study of dry and glycerol-lubricated sliding for polymethyl methacrylate (PMMA) cylinders with different surface roughness sliding on pol…

Sliding wear: role of plasticity
Ruibin Xu, B. N. J. Persson
We present experimental wear data for polymethyl methacrylate (PMMA) sliding on tile, sandpaper, and polished steel surfaces, as well as for soda-lime, borosilicate, and quartz gla…
