Abstract—In unlubricated and boundary lubricated sliding, materials touch only at a restricted numberof
isolated, typically microscopically small ‘contact spots’ that occupy but a small fraction of the
macroscopic interfacial area.The intermittent local shear strains at thecontact spots in the course
of sliding are very large. This behavior has been simulated, both for dry sliding and lubrication,
by means of stacked foils of pure copper and silver shearedunder high superimposed pressure
in a Bridgman-anvil apparatus. Strain hardening curves were obtained and the samples, now
equivalentto material at wear tracks and specifically ‘echanically Mixed Layers (MMLs), were
examined microscopically by means of a variety oftechniques.
