Poly-Ether-Ether-Ketone (PEEK) has been widely used for tribological applications with steel counterparts because of its superior mechanical and self-lubricating properties. Fluid lubrication has the potential to further improve the performance of PE

In this study, stainless steel and titanium (Ti) tubes obtained from a turbofan engine after the end of its lifetime were analyzed in order to compare the amount of pyrolytic coke present and its influence on the parent, base material. Various analyt

The rapid adoption of the advantageous PEEK/steel pairing in many tribological applications has prompted intense research to optimize its lubrication. Thus, the role of organic friction modifiers (OFMs) in improving the lubrication of PEEK-steel cont

Bearing steels suffer from a degradation of mechanical properties when atomic hydrogen diffuses into the steel from the contact surface. In rolling contact fatigue tests this can lead to a significant reduction in fatigue lives of the specimens as th

Tungsten dichalcogenides such as WS2 and WSe2 have remarkable friction reducing properties in tribological applications due to their layered structure which exfoliates easily under shear. 2H-WS2 nanoparticles (NPs) have recently been shown to possess

Hydrogen is one of the cleanest available vehicle fuels but its small atomic size allows it to diffuse readily through the lattice of solid materials, which can cause catastrophic failure in high strength steels. Metal embrittlement has been identifi
