Özet
Machine elements such as plastic-based bearings, rollers and bushings are used in machines used in different industrial sectors. The sliding speed and carrying loads of the machine elements in these applications determine the life of the material. In this experimental study carbon fiber reinforced and graphite and poly-tetra-flour-ethylene (PTFE) filled poly-ether-ether-ketone (HPV-PEEK) polymer, which is among the high performance engineering plastics used in bearings, rollers and bushings were used to determine tribological performances. AISI 304 stainless steel counter disc was used in the tests, the experiments were carried out under dry sliding conditions and at room temperature. Tribological tests were carried out on a pin-on-disc wear test machine under 3.53 MPa and at low (1.0 m/s) and high (4.0 m/s) sliding speeds. According to the wear test results, the friction coefficient decreased while wear rate values increased with the increase in sliding speed values. In general, the friction coefficient was obtained between 0.14 and 0.19, while the specific wear rate varied between 1.66x10(-6) and 0.48x10(-6) mm(3)/Nm. While abrasive wear mechanism was observed in HV-PEEK polymer at low sliding speed values, adhesive wear mechanism was observed at high sliding speed values.
