The Generation of Mechanically Mixed Layers (MMLS) During Sliding Contact

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.

Index Terms—Contact spots, Mechanically mixed layers, Bridgman-anvil apparatus
