Abstract
This study investigates the tribological behavior of polyether ether ketone (PEEK) composites with polytetrafluoroethylene (PTFE) as a solid lubricant filler under dry reciprocating sliding conditions. Polymer specimens (80% PEEK/20% PTFE and 30% PEEK/70% PTFE) were tested against a steel counterpart using a linear reciprocating tribometer. The Taguchi L4 (2³) orthogonal array was employed to evaluate the effects of load (100 N, 150 N), frequency (1.20 Hz, 2.30 Hz), and temperature (40°C, 80°C) on frictional force, coefficient of friction, and wear rate. Results showed that adding PTFE significantly reduced wear, with the 30% PEEK/70% PTFE composite achieving a minimum coefficient of friction (0.037) and wear rate (0.001 g) at 150 N, 30 Hz, and 40°C. ANOVA revealed load as the dominant factor for friction (61.28% contribution) and temperature for wear rate. Regression models predicted tribological outcomes with 99% accuracy. These findings highlight the potential of PEEK/PTFE composites for high-performance applications like bearings and seals
This study investigates the tribological performance of epoxy-based hybrid composites reinforced with ramie woven fabric and organically modified montmorillonite (OMMT) nanoclay. The composites were fabricated by incorporating different concentrations of OMMT nanoclay (3, 6, and 9 wt%) into the epoxy matrix containing...

This study investigated the effects of lubricant formulation and sliding distance on the tribological behavior of Aluminum 6061 coupled with SKD11 steel under a constant normal load of 10 N. Sliding distances of 100, 1000, and 5000 m were tested under three lubrication regimes: dry contact, waste cooking oil (WCO)-base...

In this study, the tribological performance of A7075 aluminum matrix composites reinforced with 5% B4C was investigated using the dry pin-on-disk method in accordance with the ASTM G99 standard. The effect of three different loads (10, 20, 30 N) and three different sliding speeds (1, 1.5, 2 m/s) on wear behavior was ev...

Polytetrafluoroethylene (PTFE) is widely used as a solid lubricant but suffers from poor wear resistance, limiting its application in demanding mechanical components. In this study, PTFE-based composites reinforced with polyimide (PI) pulp and graphitized carbon nanotubes (GCNTs) were prepared via a cold-press sinter...

Lightweight design is crucial for reducing inertial forces and vibrations in high-power-density reciprocating plunger pumps (RPPs). However, the tribological compatibility of lightweight alloys for crosshead–liner tribo-pairs is not well understood. This study systematically evaluates the friction and wear behaviors of...

This study investigates the tribological performance of epoxy-based composites reinforced with coir fiber and termite soil using a pin-on-disc tribometer under controlled conditions. Two formulations were evaluated: Sample A (coir/epoxy), tested at a rotational speed of 239 rpm, and Sample B (termite soil–coir/epoxy)...
