“…Referred to our previous work, 27 the followings are the preparation process of lanthanum borate nanospheres: 2.58 g La(NO 3 ) 3 •6H 2 O and 0.603 g oleic acid were well dissolved in 30 ml anhydrous ethanol, which was marked as A. Furthermore, 3.42 g Na 2 B 4 O 7 •10H 2 O were well dissolved into 30 ml distilled water, which was marked as B.…”

Vegetable oils exhibit excellent lubrication properties owing to their polar functional groups, which are liable to adsorb on the metal surfaces to form adsorption film and tribofilm. Additionally, nanoparticles play significant roles in enhancing the tribological performances of base oils by means of forming a tribofilm between friction parts. However, little work has been done on clarifying the interaction of nanoparticles and vegetable oils in the film-forming process. In this paper, two varieties of lanthanum borate nanospheres with average diameters of 50 nm (named LBN-1) and 105 nm (named LBN-2) were synthesized. The morphologies, size distribution, and chemical compositions of the nanospheres were characterized using a scanning electron microscopy, dynamic light scattering, Fourier transform infrared, and X-ray diffraction. The tribological characteristics of soybean oils with lanthanum borate nanospheres were evaluated by a four-ball tribo-tester. The tribological performances of soybean oils were obviously improved by lanthanum borate nanospheres. The focused-ion beam/transmission electron microscope analyses results revealed a uniform tribofilm containing LBN-1 was formed, contributing to excellent friction-reducing and anti-wear performances. Whereas the tribofilm of soybean oil/LBN-2 was uneven in thickness and contained more wear debris. The outcome of this work provides significant insights into the tribofilm formation for metal surfaces lubricated with vegetable oils containing different sizes of lanthanum borate nanoparticles.

“…The tribological characteristics of nanolubricants directly depend on NP size. In particular, it determines their internal mechanical and physico-chemical properties, Outstanding in enhancing friction-reduction and anti-wear capacity of rapeseed oil [160] which, in turn, affect their tribological properties. For materials in the size range of 100 nm or higher, hardness increases as particle size decreases owing to an increase in the number of dislocation pileups for crystals (Hall-Petch regime).…”

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.

“…(38)(39)(40) They also reported on the feasibility of using biodegradable lubricants to estimate the physicochemical properties of vegetable oils (41,42) and studied technical report. (43) India has also demonstrated efforts to improve environmental conditions, as some researchers have reported on the importance of using environmentally friendly lubricants. (44)(45)(46) In Indonesia, the environmental impact of lubricants does not seem to be important, as they have problems that are much more serious than lubricant contamination.…”
