Abstract

Abstract: This research article intends to portray the act of boron nitride (BN) filler (0–30 wt%), functional load, sliding speed and sliding distance on the tribological wear conduct of polyaryletherketone (PAEK). The main purpose is to investigate the impact of the above mentioned factors on the specific wear rate (Ks ). These composites are manufactured by methods for extrusion pursued by injection moulding procedure. Friction and wear failure information are gathered utilizing Pin-on-Disk wear test rig. At all tribo-test conditions, the friction coefficient ( μ ) and Ks diminishes up to 10 wt% of BN and after which it augments. Optimization of the tribological performance was directed by Taguchi plan of trials to investigate the Ks . The Ks of unfilled PAEK is in the order of 4.48 × 10 −6 mm 3 Nm −1, while the Ks of 10 and 30 wt% BN filled PAEK is 1.21 × 10 −6 and 6.22 × 10 −6 mm 3 Nm −1 correspondingly. The best outcomes are seen at a BN stacking with 10 wt%. Sliding distance was found as the most persuasive factor influencing the wear conduct of PAEK-BN composites, other variables like load, filler wt% and sliding speed likewise had a segment to play in achieving the least Ks . Worn surface morphology was contemplated utilizing scanning electron microscopy.
