Advanced Engineering Materials, Volume 28, Issue 13, 8 July 2026.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Changes in the physical state of water may alter fault frictional properties in high‐temperature geothermal systems, yet they have been little studied. Here, we perform slide‐hold‐slide experiments to examine the frictional properties (frictional strength μss and frictional healing Δμ) of chlorite‐altered basalt from Krafla Geothermal Field ...

Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels
Advanced Functional Materials, Volume 36, Issue 13, 12 February 2026.Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

RESEARCH ON DYNAMIC CHARACTERSITICS OF LINE CONTACT FRICTION PAIRS UNDER THERMAL EHL STATE
Jixie qiangdu, 2023 The line contact elasto-hydrodynamic lubrication (EHL) phenomenon generally exists in key parts of mechanical systems e. g. bearings, gears, the lubricant oil film between the contact interfaces acts as a spring and damper, and the frictional heat ...
