Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

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.

The Effect of Temperature and Physical State of Water on the Frictional Properties of Chlorite‐Altered Basaltic Gouges (Krafla Geothermal Field, Iceland)

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 ...
