Abstract : Research has been conducted on the properties of interfacial films of the kind formed in the course of sliding wear, named 'tribo-films.' Using specialized instrumentation, in particular the so-called Hoop Apparatus and a Bridgman-Anvil Device, we have found many new insights into the fundamental mechanisms responsible for the phenomena observed during sliding. In particular, advances have been made in, (1) the understanding of lubrication through adsorbed films, (2) the fundamental understanding of stick-slip, (3) the deformation mechanisms at high strains, pertinent to tribo-films and sub-surface regions, (4) micromechanisms of MoS2 lubrication, (5) understanding the implications of various materials properties for possible solid lubricants, and (6) the formation of amorphous tribo-material by high strains. The results from this contract have been documented in 14 refereed publications....
