Abstract

To study the wear behavior of polymer-steel sliding pairs, an incremental wear simulation technique had been developed, which can consider the temperature- and time-dependent behavior of polymer materials and evaluate the contact parameters (location of the contact area and the contact pressure distribution) during the wear process by changing the initial clearance between the pin and disc according to the linear wear equation. The wear simulation technique proposed is applied for a Pin-on-Disc configuration. During the wear simulation, the frictional heat generation was also considered by transient FE (Finite Element) solutions, as well as the thermal expansion in the pin-on-disc environment. The results illustrate the change of the contact parameters and the frictional heat development during the initial part of the wear process, which involves the edgelike contact and the full contact phases. Further results predict the wear process at 150 °C, based on temperature-dependent material properties and considering the creep behavior of the polyetheretherketone material. Experimental results for the worn surfaces were in good agreement with the numerical ones.
