Özet:

 In recent years, many different polymer andor polymer-based composite materials have been used in industrial areas such as machinery, food, textile and aircraftspace industries as machine elements, in bearing cages, felt, gasket and gears. One of these materials is graphite and poly-tetra-fluoro-ethylene PTFE filled polyamide-imide PAI polymer composite. It can be an alternative to traditional materials such as polyamide, poly-oxy-methylene, poly-ether-ether-ketone with its low expansion coefficient, high strength, high thermal resistance such as 275oC and chemical resistance. In this study, the wear and friction behavior of graphite and poly-tetra-fluorine-ethylene PTFE filled polyamide-imide composite were investigated. Wear and friction tests were carried out on a pin-disc tester. The experiments were carried out under constant pressure of 1.06 MPa and at four different speeds 1.0, 2.0, 3.0 and 4.0 ms. As a result of the experiments, the wear rate, friction coefficient, pin and steel disc surface temperature of the graphite and PTFE filled PAI composite PAI-GraphitePTFE were determined. With increasing sliding speed, the specific wear rate of the composite increased while the friction coefficient decreased. In addition, the composite pin and steel disc surface temperatures increased up to about 46.8 oC. The lowest wear rate of the composite was determined as 2.69x10-15 m2N, while the highest wear rate was determined as 9.2x10-15 m2N. The friction coefficient of the PAI-based composite was determined as the lowest 0.31 and the highest 0.36. In addition, the wear surfaces of the composite were examined by optical and scanning electron microscopy SEM.

 Makine, gıda, tekstil ve uçakuzay sanayi gibi endüstriyel alanlarda makine elemanı olarak, rulman kafeslerinde, keçe, conta ve dişlilerde son yıllarda çok farklı polimer veveya polimer esaslı kompozit malzemeler kullanılmaktadır. Bu malzemelerden birisi de grafit ve poli-tetra-flor-etilen PTFE katkılı poliamid-imid PAI polimer kompozitidir. Düşük genleşme katsayısı, yüksek mukavemet, 275 oC gibi yüksek ısıl direnç ve kimyasal direnç özellikleriyle geleneksel poliamid, polioksimetilen, poli-eter-eter-keton gibi malzemelere alternatif olabilecek özelliktedir. Bu çalışmada grafit ve poli-tetra-flor-etilen PTFE katkılı poliamid-imidin aşınma ve sürtünme davranışları incelenmiştir. Aşınma ve sürtünme deneyleri pim-disk test cihazında yapılmıştır. Deneyler 1.06 MPa sabit basınç altında ve dört farklı hızda 1.0, 2.0, 3.0 ve 4.0 ms gerçekleştirilmiştir. Deneyler sonucunda grafit ve PTFE katkılı PAI kompozitin PAI-GrafitPTFE aşınma oranı, sürtünme katsayısı, pim ve çelik disk yüzey sıcaklığı tespit edilmiştir. Uygulanan hızın artırılması ile kompozitin spesifik aşınma oranı artarken sürtünme katsayısı azalmıştır. Buna ilave olarak kompozit pim ve çelik disk yüzey sıcaklıkları yaklaşık 46,8 oC sıcaklığa kadar artmıştır. Kompozitin en düşük aşınma oranı 2.69x10-15 m2N olarak tespit edilirken en yüksek aşınma oranı 9,2x10-15 m2N olarak belirlenmiştir. PAI esaslı kompozitin sürtünme katsayısı ise en düşük 0.31 ve en yüksek 0.36 olarak tespit edilmiştir. Ayrıca kompozitin aşınma yüzeyleri incelemeleri optik ve taramalı elektron mikroskobu SEM ile incelenmiştir.
