dc.description.abstract <p>Because of their light weight, chemical resistance, and self-lubricating <a href="https://www.sciencedirect.com/topics/materials-science/polymer-property" title="Learn more about Polymer Property">properties, polymers</a> are used in applications ranging from biomedical to aerospace. Some polymers exhibit significant differences in <a href="https://www.sciencedirect.com/topics/engineering/wear-resistance" title="Learn more about Wear Resistance">wear resistance</a>based on whether they are in unidirectional or multidirectional sliding. Shear induced polymer chain orientation is believed to be responsible for this behavior. <a href="https://www.sciencedirect.com/topics/materials-science/polyetheretherketone" title="Learn more about Polyetheretherketone">Polyetheretherketone</a> (PEEK) has excellent wear resistance, but its multidirectional sliding behavior has not been thoroughly investigated. A factorial multidirectional pin-on-plate wear study of PEEK was conducted with a focus on molecular weight and sliding path <a href="https://www.sciencedirect.com/topics/engineering/directionality" title="Learn more about Directionality">directionality</a>. These factors were studied for their correlation to over all wear performance. Additionally, transfer <a href="https://www.sciencedirect.com/topics/materials-science/film-thickness" title="Learn more about Film Thickness">film thickness</a> was measured at locations along the wear path using white light <a href="https://www.sciencedirect.com/topics/chemical-engineering/interferometry" title="Learn more about Interferometry">interferometry</a>. Wear in PEEK was shown to depend significantly on path shape and direction. The lowest wear configuration also resulted in quantifiably thinner and more continuous transfer films. A result of this work has been a greater understanding of PEEK wear mechanisms in various sliding configurations.</p>
