This work focuses on a study of the parameters affecting the running-in and long-term behaviour of plastic/plastic and plastic/steel contacts at sliding distances sufficiently long to ensure steady-state sliding conditions, which is very important for an evaluation of the performance in real-scale applications. Unreinforced polyamide (PA6) was paired against stainless steel and against unreinforced polyacetal (POM). The effect of sliding velocity was studied at a constant nominal pressure of 0.7 MPa. The results show that the running-in sliding distances to reach steady-state conditions are much longer for the PA6/POM contacts than for the PA6/steel contacts.against the steel surfaces.
