Abstract

Farklı endüstriyel sektörlerde kullanılan makinalarda plastik esaslı rulman, makara ve burç gibi makine elemanları kullanılmaktadır. Bu uygulamalardaki makine elemanlarının çalışma esnasındaki hızları ve taşıma yükleri malzemenin ömrünü belirlemektedir. Bu deneysel çalışmada, rulman, makara ve burç yapımında kullanılan yüksek performanslı mühendislik plastikleri arasında yer alan karbon fiber takviyeli grafit ve poli-tetra-flor-etilen (PTFE) katkılı poli-eter-eter-keton (HV-PEEK) polimeri kullanılarak tribolojik performansları incelenmiştir. Testlerde AISI304 paslanmaz çelik karşı disk kullanılmış, deneyler kuru kayma şartları altında ve oda sıcaklığında yapılmıştır. Aşınma deneyleri, 3.53 MPa basınç altında, düşük (1.0 m/s) ve yüksek (4.0 m/s) kayma hız aralıklarında pim-disk aşınma test cihazında gerçekleştirilmiştir. Aşınma test sonuçlarına göre, kayma hızına bağlı olarak HPV-PEEK polimerinin sürtünme katsayısı ve spesifik aşınma oranı değişimi incelenmiştir. Elde edilen deney sonuçlarına göre artan kayma hızı ile birlikte polimerin sürtünme katsayısı azalırken spesifik aşınma oranı değerleri artmıştır. Genel olarak sürtünme katsayısı 0.14 ile 0.19 aralığında elde edilmiş, aşınma oranı ise 1.66×10-6 ile 0.48×10-6 mm3/Nm aralığında değişim göstermiştir. Deneylerde kullanılan HV-PEEK polimer kompozitinde düşük kayma hızlarında abrazif aşınma mekanizması gözlenirken yüksek kayma hızlarında adhezif aşınma mekanizması gözlenmiştir.

Determination of the Effect of Sliding Speed on Tribological Performances of Carbon Fiber Reinforced, Graphite and PTFE Filled Poly-ether-ether-ketone (PEEK) Polymer Composite

Abstract

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 1.66×10-6 and 0.48×10-6 mm3/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.
