    The effect of water lubrication on polymer wear under rolling contact conditions (1994)

    Notes: The results of studies into the performance of three selected engineering polymers in rolling contact are presented. Both dry and water lubrication conditions were used. The polymers were machined into a cup simulating the outer race in a rolling contact bearing. Ceramic balls were used in order to create corrosion resistant combinations of materials. Post-test studies were carried out using a scanning electron microscope. On the basis of microscopy examinations the effect of water on the morphology of contact path surfaces was assessed and the abilities of tested polymers to operate in the presence of water in a rolling contact were ranked. © 1994 John Wiley & Sons, Inc.

    Mode of loading and contact configuration effects in the wear of polymers (1996)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Results of an experimental study into the relationship between the wear of PMMA and the mode of loading and contact configuration are presented. It was found that the wear of PMMA under cyclic loading is significantly lower than is the wear under static loading of a magnitude equal to the mean load of the cycle. Different contact configurations, represented by the angle between the axis of the PMMA sample and the axis of the steel disc(counterface), proved to have only a minor effect on the wear of PMMA. The lowest wear rate for both static and cyclic loading was obtained for smaller angles. © 1996 John Wiley & Sons, Inc.

    External lubrication of high-temperature thermoplastic polymers (1993)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 48 (1993), S. 897-904

    Notes: External lubrication of high-temperature thermoplastic polymers was studied experimentally. It was found that the nature of the lubrication fluid has a pronounced effect upon the behavior of the contact. It is postulated that premature failure of PEEK-lubricated contacts is caused by the migration of linear carboxylic acids into the polymer matrix at elevated temperatures, thereby producing significant plasticization. A sequence of events leading to failure is given and some rationale for it provided. © 1993 John Wiley & Sons, Inc.

    Morphology of polymer wear debris resulting from different contact conditions (1992)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: An investigation into the wear process of five polymers tested under different contact conditions is presented. Polymer pin on metal plate and metal pin on polymer plate configurations were used. The metal pin on polymer plate configuration gave significantly lower wear rates compared to that observed for the polymer pin on metal plate configuration. The results are discussed in terms of morphology of wear debris generated.

    Phenomenology of surface failure of poly(methylmethacrylate) resulting from rolling contact fatigue (1995)

    Notes: Results of phenomenological study into the forms of surface failure of poly(methylmethacrylate) (PMMA) are presented. Surface failure of the polymer resulted from rolling contact fatigue produced in a model configuration consisting of a PMMA disc with nominally flat surface loaded against three steel balls able to roll free over the surface of the disc. It was found that the performance of the polymer under the test conditions used is influenced by lubricating medium and the main form of failure is of surface fatigue type. © 1995 John Wiley & Sons, Inc.
