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....
