The study of lubricating oil is paramount for the optimal functioning of modern engines, and it has generated intensive research in the automotive industry. The aim is to improve the tribological properties of lubricants by including nanomaterials as additives in base oils. This article presents an exhaustive bibliographic review of the experiments carried out to optimize the tribological properties of nano-lubricants in order to identify the nanoparticles and experimental processes used and analyze the results obtained. The methodology adopted combines inductive and deductive elements. It begins with the formulation of a general theory on the application of nanoparticles in lubricants, followed by the collection of specific data on the conceptualization and preparation of nano-lubricants. A total of 176 articles focused on the application of nanoparticles in lubricants, especially to reduce the coefficient of friction, are reviewed. These works, with impact levels Q1 and Q2, delve into the application and are analyzed to review the obtained results. Most researchers worked with a nanoparticle concentration range of 0% to 1% by volume.

“…These mechanisms vary for different nanoparticles [ 28 ]. It has been found that the adsorption of nanocomposite carbon additives on the interacting surface enhances the tribological performance of SN/GF-5 lubricants [ 17 ]. WS 2 (tungsten disulfide) nanoparticles form a protective layer and cause a patching effect, making the interacting surfaces smoother, which in turn leads to improved tribological properties of lubricant oil [ 29 ].…”

“…To date, a number of nanoparticles have been used with various base oils, and the effects on the wear and friction performance of these base oils have been studied [ 8 , 9 , 10 , 11 ]. Those nanomaterials that are most used as lubricant additives include graphene [ 12 , 13 , 14 ], graphene oxide [ 15 ], carbon nanotubes [ 16 , 17 ], boron nitride [ 18 ], silicon dioxide [ 19 ], copper oxide [ 20 ], and titanium dioxide [ 21 ]. Additionally, a few studies have also been conducted on combinations of different nanomaterials (hybrid nanoparticles) as lubricant additives [ 22 , 23 , 24 ].…”

A Review of Friction Performance of Lubricants with Nano Additives

et al. 2021

View full text Add to dashboard Cite

It has been established in literature that the addition of nanoparticles to lubricants at an optimum concentration results in a lower coefficient of friction compared to lubricants with no nanoparticle additives. This review paper shows a comparison of different lubricants based on the COF (coefficient of friction) with nanoadditives. The effect of the addition of nanoparticles on the friction coefficient was analyzed for both synthetic and biolubricants separately. The limitations associated with the use of nanoparticles are explained. The mechanisms responsible for a reduction in friction when nanoparticles are used as an additive are also discussed. Various nanoparticles that have been most widely used in recent years showed good performance within lubricants, including CuO (copper oxide), MoS2 (molybdenum disulfide), and TiO2 (titanium dioxide). The paper also indicates some research gaps that need to be addressed.

“…Nanomaterials [32], such as activated carbon nanoparticles [33], boron nitride [34], carbon nanotubes [35,36], graphene and its oxide [37][38][39], are considered as more eco-friendly anti-wear (AW) and extreme pressure (EP) additives to lubricants. Effective AW agents represented in metal oxide nano-additives, such as titanium dioxide [40,41] and ZnO [42][43][44], act as antioxidants in order to stabilize the physical properties of oil under harsh conditions.…”

Palm oil possesses promising properties which promote them to be a competitive alternative to mineral oils in the lubrication of machinery. Still, marginal oxidation stability, viscosity, and tribological properties remain critical issues for performance improvement. This paper synthesized palm grease with reduced graphene oxide (rGO) and zinc oxide (ZnO) nano-additives at different blending ratios. Grease samples were tested for the physicochemical and tribological characteristics. The results showed that the highest viscosity values are found in case of base oil mixed with 0.1 wt.% ZnO and 2 wt.% rGO, separately. ZnO additives enhanced the oxidation stability by 60% and shifted the pour point from 9 oC to 6 oC. Adding ZnO and rGO to the palm grease increased the load-carrying capacity between 30% and 60%, respectively, and reduced the friction coefficient by up to 60%. The wear scar morphology proved a high competency of the developed palm grease aggregates in comparison with lithium grease.
