The CNFs could also act as solid lubrication and anti-friction agent in the composites.
This free carbon on top of the surface layers can act as solid lubricant reducing wear rate.
These results act as solid evidences to highlight the crucial role of particles for developing composite hydrogels with desire thermosensitivity and mechanical properties for use in bioengineering applications.
Transfer films have been engineered to act as solid lubricants between sliding surfaces in environments where fluids cannot exist or are not desired.
In addition, B4C coatings annealed at 600 °C, form a layer that acts as solid lubricant leading to a low coefficient of friction, COF, against titanium.
In that case, they acted as a solid lubricant to reduce both wear and scuffing.
The in situ formed tribofilm also lowered the coefficient of friction and acted as a solid lubricant between the two interacting metal surfaces.
It has also been found that plasma sulfnitrided sample revealed better wear resistance due to the presence of the thin FeS layer which acted as a solid lubricant.
It was worth pointing out that the metallic Au species not only acted as the solid state electron mediator, but also could absorbed photons from incident light and present surface plasmon resonance effect in this hybridization system.
SEM and EDS analyses indicated that the continuous and uniform transfer film generated on counterfaces acted as a solid lubricant, which was important to improve the self-lubricating property of PTFE/serpentine nanocomposite.
