this study compares the tribological and thermophysical features of the lubricating oil using MoS 2 and Zno nano-additives. the average size of MoS 2 and ZnO nanoparticles were 90 nm and 30 nm, respectively. The nanoparticles were suspended using Triton X-100 in three different concentrations (0.1, 0.4 and 0.7 wt.%) in a commercial diesel oil. Tribological properties such as mass loss of the pins, friction coefficient, and worn surface morphologies and thermophysical properties such as viscosity, viscosity index, flash point and pour point of resulting nano lubricant were evaluated and compared with those of pure diesel oil. the tribological behavior of nano lubricants was evaluated using a pin-ondisc tribometer. the worn surface morphologies were observed by scanning electron microscopy. the overall results of this experiment reveal that the addition of nano-MoS 2 reduces the mass loss values of the pins in 93% due to the nano-MoS 2 lubricant effect. With 0.7 wt.% in nanoparticles content, the viscosity of MoS 2 and ZnO nano lubricants at 100 °C increased by about 9.58% and 10.14%, respectively. Pure oil containing 0.7 wt.% of each nanoparticle increased the flash point because of its small size and surface modifying behavior compared to the pure oil. Moreover, the addition of Zno nanoparticles with pure oil lubricant is more suitable than MoS 2 nanoparticles for improving the thermophysical properties of pure oil.

The effect of nanoparticle-added solid lubricant on the formability of sheet metal

In sheet metal forming processes, formation without fracture is related to sheet metal formability. Parameters such as tool geometry, blank holder force, and lubricant are changed in order to push the formability of material to its maximum capacity. Lubricants play an important role in sheet metal forming processes. Depending on the type of lubricant, the formability of the sheet metal can be increased, the surface quality of the product can be improved, and the tool life can be extended. In this study, nanoparticles were added to solid lubricants, and the effect of nanolubricants on sheet metal formability was investigated with Erichsen test. Test specimens were observed by SEM, and the nanoparticle effect was investigated by EDX mapping. In addition, the optimum nanoparticle concentration was determined, and the effects of the nanoparticle on solid lubricants were compared with other lubricants which were used in sheet metal forming. As a result of the study, it was observed that the nanoparticle additive increased the formability by 13%. Results showed that the formability of the sheet metal increased up to certain nanoparticle concentrations, but it decreased above this limit.

“…To date, a large number of nanomaterials used as additives to lubricating oils, in particular, carbon materials [23,24], carbon nanotubes [25], graphene oxide [26][27][28], boron nitrides [29,30], and silicon oxide [31], have been obtained. However, the most extensive studies have been carried out with metal-containing nanomaterials, whose NPs contain, e.g., metals, their oxides, and sulfides [32][33][34].…”

This review focuses on the effect of metal-containing nanomaterials on tribological performance in oil lubrication. The basic data on nanolubricants based on nanoparticles of metals, metal oxides, metal sulfides, nanocomposities, and rare-earth compounds are generalized. The influence of nanoparticle size, morphology, surface functionalization, and concentration on friction and wear is analyzed. The lubrication mechanisms of nanolubricants are discussed. The problems and prospects for the development of metal-containing nanomaterials as lubricant additives are considered. The bibliography includes articles published during the last five years.
