“…Meanwhile, the practical application research on PEEK's tribological fatigue fracture of the combination between PEEK plastic and ceramic part is only few studies [7][8][9]. In the previous study, we reported that the subsurface crack propagated along the PEEK shaft rolling direction in terms of fatigue failure mechanism when cyclic compressive stress was applied to the PEEK shaft [9].…”

Abstract. Subsurface fatigue cracks under rolling contact area of the PEEK shaft against an alumina bearing's ball were investigated for application of frictional part in mechanical element in special situations such as chemical environments. In order to explore the flaking process of the PEEK shaft, the rolling contact fatigue tests were carried out by using a one-point radial loading rolling contact machine. The flaking occurred on the rolling track of the PEEK shaft at approximate 4×10 5 fatigue cycles. The subsurface fatigue crack propagation was investigated by using 2.5-Dimension layer observation method. The flaking was caused by the propagations of surface cracks and subsurface shear cracks, and the flaking shape was half-ellipse. Moreover, beach marks as fatigue crack propagation in the flaking were observed.

“…In the bulk or pristine form, only a few polymers would satisfy most of the tribological requirements; however, in their hybrid and composite forms, polymers often have the advantage of low weight and corrosion resistant over other materials such as metals and ceramics [1]. Tribological applications of polymers include gears [2], a range of bearings [3], artificial human joint bearing surfaces [4], bearing materials for space applications [5], tires, shoe soles, automobile brake pads, non-stick frying pans, floorings, and various types of surfaces for optimum tactile properties, such as fibers [6]. Similar to the bulk mechanical responses, tribological characteristics of polymers are greatly influenced by temperature, relative speed of the interacting surfaces [7], the normal load [8], and the environment [9].…”

Reinforced polymer-matrix composites are widely used under sliding contact conditions in various boating and automotive applications. In this paper, the friction and wear of bulk epoxy and carbon filler reinforced epoxy composites have been investigated using a pin-on-disc tribometer. The effect of different fillers on the tribological behavior of an epoxy has been studied using treated and untreated carbon nanotubes, graphite, and a mixture of graphite and carbon nanotubes. Filler addition greatly enhances the tribological properties of the epoxy resin, by reducing the friction coefficient and the wear rate. In addition, it was found that the treated carbon nanotubes/epoxy composites have the best tribological behavior. Moreover, a correlation between contact temperature and friction coefficient is reported. Finally, the wear mechanisms were determined by scanning electronic microscopy.

Recent advances in polymer nanocomposites open a wide range of applications in various industrialsectors. Due to their high potential properties, these materials are replacing the usage of metals for many heavier components in automobile industries. In this experimental work, the tribological performance of Graphene oxide (GO) -Polyamide is investigated against pristine polyamide by fabricating gears for the usage in engineering applications. A gear test rig was developed in-house for analysis to study the speci¯c wear rate and temperature gradient at di®erent conditions of load and speeds. The wear resistance of the polyamide gears with the addition of 0.03 wt.% of graphene oxide is better than the pristine polyamide gears and the speci¯c wear rate is reduced signi¯cantly. The reduced speci¯c wear rate of these polymer nanocomposite gears is attributed to the superior properties of graphene oxide such as High speci¯c surface area, good adhesion properties and enhanced glass transition temperatures. The GO nanocomposite gear seems to be a potential alternative against conventional gears for engineering applications. Finally, the wear mechanisms and the potential of GO-based polyamide nanocomposite gears were proposed tentatively in the development of transmission gears for engineering applications. Surf. Rev.
