“…In recent years, the field of tribology has received rapid positive attention since poor lubrication has evidently show loss of energy and waste of resources resulting from severe friction and wear [6][7][8][9] . Solving this unwanted friction and wear during system operation, which stands as the most confronted challenges during system working operation 10) . Tribologists have come up with three possible approaches in mitigating the problems.…”

“…Presence of material with good thermal properties and lubricant enhancement features, between the two sliding surfaces in contact, apparently is the possible method of mitigating the unwanted friction, thus prevent wear occurrence 5,10,16,23) . Furthermore, the use of a proper lubricant in both industrial and domestic applications can serve as debris removers and provide cooling to the machine through surfactant operation 24) .…”

Wear on the other hand refers to as physical loss of machine element materials resulting from poor function of interfacial fluid film of the lubricant 10) . The wear of element materials arises from different factors like; contact fatigue, adhesion, corrosion and abrasion resulting from poor lubricant (base oil and additives) 30,32) , which are normally provided by nanofluid.…”

Nanoparticles (NPs) additives have gained notable influence in technology advancements owing to their excellent physiochemical properties with enhanced performance in application compared to previously used additives. The field of tribology has contributed significantly towards upgrading the overall engine efficiency through use of lubricating materials. The outstanding technique in achieving this is through adoption of additives derived from nanotechnology capable of preventing friction and wears during engine operations. Since only base oil cannot withstand most of the operating conditions, suitable additives are formulated and blended as to enhance the tribological properties. According to some research, nanoparticle additions have a greater impact on lubricant improvement. The ability to design NPs additives with unique qualities raises the value and demand for such class of products. The purpose of this study is to highlight the promising properties of NPs additives, mechanisms and to define the specific knowledge gaps related to the size of NPs towards friction and wear reduction. The function and mechanism performance of NPs additives during operation, such as mending, rolling, film formation, and polishing effect, is determined by their types. The excellent load carrying capability of nanoparticles during lubrication reflects their outstanding performance. The review presents an overview of the history and classifications of NPs and concisely elucidate their tribological effect when applied in lubrication. Excellent function of nano additives is the attribute of its nanoscale (1 to 100 nm) nature, thus categorized base on their size, shape, origin and composition. Certain expected characteristics of lubricating oil like friction and wear resistance, surfactant operation, load carrying capacity, extreme pressure operation, etc. were achieved through inclusion of nanoparticles additives.

Minimizing friction and wear in between mating parts is the main concern in the field of tribological studies. Lubricants with improved tribological properties are continuously explored for minimizing friction and wear. In the present work, an attempt has been made to evaluate the effect of the addition of aluminium oxide (Al2O3) nanoparticles as lubricant additives on the tribological performance of base lubricant oil (SAE10W40) using four-ball tester. Weight in the percentage of Al2O3 nanoparticles was added in base oil and evaluated the effect of additives on wear preventive characteristic and coefficient of friction of base lubricant oil. Integrated Taguchi-Grey relational approach is implemented to obtain the optimum combination of load and % wt. of Al2O3 nanoparticle addition for improving the tribological performance of base lubricant oil. With a load of 250 N and 0.5 wt% of Al2O3 nanoparticles shows an optimum combination for the improved tribological performance of base oil. The wear scar diameter and coefficient of friction found to be reduced by 20.75 % and 22.67 % respectively with the addition of 0.5 wt% of Al2O3 nanoparticles in base lubricant oil. The lubrication performance seems to be improved because of mending effect and ball bearing effect of Al2O3 nanoparticles forming a self-protective film on the friction surface.

In the following study, green carbon nanotubes and green few-layer reduced graphene oxide (rGO) were synthesized through simple, sustainable, and scalable processes starting from recycled plastic and charcoal, respectively, and with the highest number of steps involving non-harmful substances. After an extensive physicochemical characterization, which evidenced that both nano-carbons exhibit structures comparable with that of materials produced through more traditional methods and from pure sources, the samples were dispersed in two types of conventional base oils, in particular group I and group III, in order to carry out, for the first time on these green nanomaterials, an accurate study on their tribological performance. Tribological tests evidenced a remarkable reduction of coefficient of friction and wear scar diameter, especially for the green rGO dispersed at 0.1 wt% in the group III oil along with SDBS-Tween 80 surfactants mixture: 18% and 15% at ambient temperature, 12% and 13% at 80 °C, respectively. Furthermore, the tribological performance of the synthesized samples in both oils remained high for 160 min of investigation. A comparison with the same material obtained with a traditional synthesis revealed the absence of fouling phenomena in the lubrication chambers in our case, confirming the higher tribological performances of the green rGO sample, probably, as a consequence of its less ordered nature.
