“…Among nanoparticle-based lubricants, hexagonal boron nitride (hBN) is a substance being studied with increasing interest. [15][16][17][18][19][20] hBN exhibits a laminated structure with an ultra-flat surface like graphite. Strong covalent boron-nitrogen bonds form the layer; weak Van der Waals force exists between layers.…”

“…21 hBN is suitable for hot and cold processes because of low thermal expansion, high thermal conductivity, and low dielectric constant. 22 hBN is a cheap lubricant that has better biodegradability and exhibits superior tribological properties upon mixing with conventional engine oils 15,16 or vegetable oils [17][18][19] or water. 20 Several mechanisms have been proposed to explain how nanolubricants improve lubrication; some of these include protective film creation, rolling effects, mending, and polishing effects.…”

This study intends to explore the lubrication mechanism of hexagonal boron nitride nano-additive. Synergistic analysis comprising worn surface observation, surface wettability testing, and the Stribeck curve principle is used to test this water-based lubricant on steel–steel contact. Distilled water and 0.1–5.0 vol.% hexagonal boron nitride nano-additive is used to prepare a mixture using sonification technique. A viscometer is employed to determine the viscosity of the nanolubricant. A four-ball tribometer is employed to determine the tribological characteristics and lubrication performance. Hamrock and Dowson equations are used to determine the minimum film thickness needed for lubrication. Surface morphology characteristics are inspected using energy-dispersive X-ray spectroscopy, scanning electron microscopy, surface tension meter, and profilometer. The efficacy of the lubricant as friction and wear-reduction additive is determined to have a mixed lubrication regime with the optimum concentration of 1.0 vol.% hexagonal boron nitride. Protecting film, mending effect, rolling effect, and polishing effect have been recommended as the lubrication mechanisms. Increasing the addition of hexagonal boron nitride additives may lead to a change in the lubrication regime from mixed to hydrodynamic, where agglomeration is observed in the nanoparticles, and an increase in friction is observed.

“…In previous research works performed by various authors, palm oil had been proved to be a promising potential replacement to synthetic oils which is more superior to conventional cutting fluids in machining industries [ 177 – 180 , 181 ]. Palm oil is one of the recent choices from list of vegetable oils to be studied as potential low cost, efficient cutting fluids for MQL-assisted machining.…”

This paper reviews recent progress and applications of usage of cutting fluids in conventional machining processes. In addition to reviewing the various conventional and advanced cooling techniques during machining, the paper also discusses the use of minimum quantity lubrication (MQL) in several types on metals such as steel, aluminum, alloy, and titanium alloys. Due to the toxicity of conventional cutting fluid resulting in ecological problems, the demand for environmentally friendly cutting fluid is rising. Therefore, natural vegetable oil is chosen as potential replacement as an environmentally friendly cutting fluid which fulfills the important aspects of biodegradability and sustainability. Application of vegetable oil-based cutting fluids under MQL techniques are also discussed. Moreover, the potential of palm oil as biodegradable and environmentally friendly natural vegetable oil-based metal-working fluids in MQL are reviewed.

“…Bio-lubricants made by using vegetable oils, such as the palm oil, which were mixed with the hexagonal boron nitride (hBN) nanoparticles were seen to significantly improve the friction and the wear of the sliding components that were used for different applications. The earlier studies stated that palm oil mixed with an hBN nanoparticle concentration ranging 0.05–0.5 Vol.%, could effectively decrease 20% of the wear and friction of all sliding components, in comparison to the traditional oils (Abdollah et al , 2020; Talib and Rahim, 2018; Talib et al , 2017).…”

Purpose This study aims to introduce a novel technique which helped in quantifying the wear performance of a roller chain which was lubricated by using the palm oil-based hexagonal boron nitride (hBN) nanoparticles (nano-biolubricant). Design/methodology/approach The efficiency of the nano-biolubricant was evaluated by using a custom-made roller chain tribometer, at different resistance torque values at a constant speed and running time. Prior to the test, 2 different lubrication conditions were applied. The mass loss and elongation behaviour of a roller chain was selected as a degradation metric for monitoring the amount of the chain wear. The predominant wear mechanism of a roller chain was identified by surface morphological analysis. Findings Regardless of the lubrication conditions, the wear performance of the roller chain was significantly increased, at increasing resistance torque values. Higher wear was noted when the roller chain was lubricated using a nano-biolubricant, however, the wear curve showed a promising high chain life. The predominant wear mechanism involved is abrasive wear. Originality/value Although an increase in the elongation during running is based on the wear between the pins and roller, none of the earlier studies quantified the wear performance of a roller chain under differing lubrication conditions. Hence, for bridging the gap, this study described a new method for measuring the wear performance of the roller chain which was lubricated using the palm oil-based hBN nanoparticles or a nano-biolubricant.
