Tribological Performance of POM, PTFE and PSU Composites Used in Electrical Engineering Applications

In this experimental study, the tribological performance of polysulfone, poly-tetra-fluoro-ethylene, poly-oxy-methylene composites sliding against a poly-phenylene-sulfide polymer composite was studied. Tribological experiments were run under dry ambient conditions and at sliding speeds of 0.5-1.5m/s under nominal load values of 20-40N. Results for tested materials showed for the range of applied load and sliding speed values of this investigation that the friction coefficient and the wear rate are much more sensitive to the change in sliding speed rather than to the change in applied load values. The wear mechanism is mainly an adhesive process, but includes some abrasive process as well.
