Tribological properties of oleic acid-modified …

2011-5-3 · Graphene additive in oil will protect the contact metal surfaces of friction pairs, leading to a reduction of A f and an increase in A o, further reducing the frictional resistance and wear. Therefore, FC is markedly reduced at lower concentrations compared with that in pure oil. As the graphene concentration increases, graphene piling-up ...

The Tribological Properties of Multi-Layered …

Multi-layered graphene was prepared by supercritical CO2 exfoliation of graphite. As the additives of polyalphaolefin-2 (PAO2) oil, its tribological properties were investigated using four-ball test method. The friction reduction and anti-wear ability of pure lubricant was improved by the addition of graphene. With a favorable concentration, the graphene was dispersive.

The Critical Role of Graphene as Nano Friction …

2020-12-10 · Mechanism of n ano friction reducer oil additive. A large number of experimental studies have found that as an oil additive, nanoparticles can effectively improve the lubrication state of the friction pair and reduce friction and wear. It is an ideal friction-reducing oil additive. However, due to the limitations of modern science and ...
