Abstract

Plastic-based bushings and bearings are used in some parts of the machines used in different sectors of the industry. In applications where high temperature, corrosion, chemical resistance and wear resistance are required, choosing a right material is very important for the service life of the machine element. In this study, the tribological performances of pure poly-ether-ether-ketone (PEEK) polymer and 30% by weight glass fiber (GF) reinforced poly-ether-ether-ketone (PEEK-30GF) composite were investigated. The materials used in the experiments are in the form of rods produced for industrial purposes by the extrusion method. Tribological experiments were carried out 2000 m under dry sliding conditions at room temperature using a pin-on-disc wear test device. Two different loads (30 N and 60 N) and four different speeds (1, 2, 3 and 4 m s-1) were used in the experiments. As a result of the experiments, the friction coefficient, pin temperature and specific wear rate of pure PEEK polymer and 30% glass fiber reinforced PEEK composite were determined. As a result of the experiments, with the increase of the sliding speed, the wear rate of both pure PEEK and glass fiber reinforced PEEK composite increased, while the friction coefficient values decreased. At low load (30 N) and speed (1 m s-1), PEEK composite was found to be 2.46 times more wear resistant than pure PEEK polymer. In addition, microstructure examinations of the wear surface of the test materials were carried out using an optical microscope. Adhesive wear at low loads and speeds and abrasive wear mechanisms at high speeds and loads were observed for both test materials.

Özet

Endüstrinin değişik sektörlerinde kullanılan makinaların bazı aksamlarında plastik esaslı burç ve yataklar kullanılmaktadır. Yüksek sıcaklık, korozyon, kimyasal direnç ve aşınma direnci istenen uygulamalarda doğru malzeme seçimi, makina elemanının çalışma ömrü açısından oldukça önemlidir. Bu çalışmada, saf poli-eter-eter-keton (PEEK) polimeri ile ağırlık olarak %30 oranında cam elyaf (CE) takviyeli poli-eter-eter-keton (PEEK-30CE) kompozitin tribolojik performansları araştırılmıştır. Deneylerde kullanılan malzemeler, ekstrüzyon yöntemiyle endüstriyel amacıyla üretilmiş çubuk formunda malzemelerdir. Tribolojik deneyler disk üzerinde pim cihazı kullanılarak oda sıcaklığında 2000 m kuru kayma şartlarında gerçekleştirilmiştir. Deneylerde iki farklı yük (30 N ve 60 N) ve dört farklı hız (1, 2, 3 ve 4 m s-1) kullanılmıştır. Deneyler sonucunda saf PEEK polimer ve %30 oranında cam elyaf takviyeli PEEK kompozitinin sürtünme katsayısı, pim sıcaklığı ve spesifik aşınma oranı belirlenmiştir. Deneyler sonucunda kayma hızının artması ile hem saf PEEK hem de cam elyaf takviyeli PEEK kompozitin aşınma oranı artarken sürtünme katsayısı değerleri ise azalmıştır. Düşük yük (30 N) ve hızda (1 m s-1) PEEK kompoziti saf PEEK polimerine göre 2.46 kez daha aşınma dirençli olduğu tespit edilmiştir. Ayrıca optik mikroskop kullanılarak deney malzemelerinin aşınma yüzeyi mikroyapı incelemeleri gerçekleştirilmiştir. Her iki deney malzemesi için düşük yük ve hızlarda adhezif aşınma, yüksek hız ve yüklerde ise abrazif aşınma mekanizması gözlenmiştir.
