Effect of wear particles and roughness on nanoscale friction [PDF]
Phys. Rev. Mater. 6, 013606 (2022), 2021 Frictional contacts lead to the formation of a surface layer called the third body, consisting of wear particles and structures resulting from their agglomerates. Its behavior and properties at the nanoscale control the macroscopic tribological performance.

Direct microscopic evidence of shear induced graphitization of ultrananocrystalline diamond films [PDF]
, 2021 The origin of ultralow friction and high wear resistance in ultrananocrystalline diamond (UNCD) films is still under active debate because of the perplexed tribochemistry at the sliding interface. Herein, we report a comparative study on surface topography and nanoscale friction of tribofilms, in wear tracks of two sets of UNCD films having different ...
