Abstract Developing lubricants with good electrical conductivity and tribological properties is necessary for the power equipment. Here, niobium selenide (NbSe 2 ) boron nitride (BN) were employed to act as additives fabricate lubricating greases superior properties. The grease containing different concentrations of synthesized their conductivities measured by a volume resistance meter at room ...

This work focused on the experimental study of grease lubrication mechanisms around contacts in radial ball bearing 6314. The main objective this was to show influence conformities and their impact bearings. For experiments, a tribometer ball-on-ring configuration used fluorescence microscopy chosen as observation method. results showed that, under starvation conditions, conformity 0.52 at velo...

Splines are irreplaceable in high-speed aviation fields due to their simplicity, reliability, and high specific power. Aviation splines not only subjected severe operating mechanical loads, but also sometimes operate under grease-lubricated non-lubricated environments. All of this results suffering widespread failures. Since the 1960s, many researchers have carried out much research on splines....

Nanoparticles have as characteristics super sliding, extreme pressure, self-healing, etc., which can improve the friction reduction and anti-wear performance of sliding components, when used lubricating oil additives. Nano-copper particles a good synergistic effect with other antifriction agents, antioxidants grease additives because their low shear strength grain boundary slip effect, showing ...
