In the present study three different high performance composite polymers, with PTFE filling, are investigated experimentally regarding their applicability in dry rolling/sliding contacts against steel counterparts. Special attention is attributed to the influence of the counterpart's surface roughness on experimental performance. Also, the influence of electroless nickel platings on the tribo-system, is thoroughly investigated. A pin-on-plate test setup, with reciprocating motion and a two-disc machine, are employed for the experimental part of this study. Microscopical analysis are carried out in order to gain a profound understanding of phenomena taking place in the contact zone. Results indicate that PTFE plays a key role for the functionality of these systems. Also, the roughness of the counterparts strongly affects wear and friction, whereby a finer surface is not necessarily improving these characteristics. The electroless nickel plating is found to have very beneficial effects on overall performance under certain circumstances.
