“…Poly-ether-ether-ketone (PEEK) has high chemical resistance, self-lubrication ability, no degradation risk in salt water, and non-electrical conductivity. Researchers investigated tribological failures of PEEK materials for frictional parts used under rolling contact fatigue (RCF) [3,[5][6][7]. Flaking as tribological fatigue failure causes noise, vibration, or alignment error in components, which is an important quality problem for products.…”

“…[6]. Avanzini et al reported that in RCF between a PEEK roller and a steel disk micro-pitting and transversal crack on the rolling surface of the roller edge occurred due to tangential stress [7]. Dearn et al reported that the location of the maximum shear stress depended on the friction condition and was related with the fracture of PEEK polymer gears [8].…”

The growth of flaking as tribological fatigue failure in PEEK was investigated through the one-point type rolling contact fatigue test between a machined PEEK polymer shaft and an alumina bearing's ball. Due to Hertzian contact of cyclic compressive stress, the subsurface fatigue cracks in the PEEK shaft propagated in rolling and axial directions. When the rolling fatigue life of the PEEK shaft reached 106 fatigue cycles, many narrow angled cracks occurred in the near-surface of the rolling track without flaking. On the other hand, when the flaking ocuurred on the PEEK shaft before 106 fatigue cycles, semicircular surface and subsurface crack propagations were observed. From these observations, it was found that micro-flaking occurred due to the linkages between subsurface and surface cracks. Flakingdeveloped due to the accumulation of these micro-flakings.
