Total internal reflection (TIR) Raman tribometer: a new tool for in situ study of friction-induced material transfer
Abstract
The sliding history in friction-induced material transfer of dry 2H-MoS2 particles in a sheared contact was studied. Video images in contact showed fragmentation of lubricant particles and build-up of a transfer film, and were used to measure the speed of fragmented particles in the contact region.
