“…Numerous works have reported a biolubricant filled with cellulose [24][25][26]. Recent research which is relatively similar to our present investigation has quantified the characterization of biolubricant mixed with cellulose from plant [12,27,28]. However, the study on tribology performance and viscosity of POE-based biolubricant mixed with NDCt as an additive and Span 60 as a surfactant is yet to be explored.…”

“…The coefficient of friction (COF) along the cycle number for each sample is displayed in Figure 7. The PO without filler shows the rougher curve during the running-in period probably because of higher friction between the ball and disk surface [12]. After the addition of fillers (NDCt and Span 60) in POE, the curve became smoother due to lower friction.…”

“…Ecofriendly additives from sustainable sources are considered more by researchers rather than conventional additives [8,10,11]. A recent study has explored cellulose from the plant as an additive of biolubricant for improvement of its tribology performance [12]. Generally, isolation of the nanocellulose used a chemical treatment.…”

This research is aimed at studying the stability and tribology properties of the polyol ester oil- (POE-) based biolubricant mixed with various filler loadings from microparticle of TEMPO-oxidized bacterial cellulose (NDCt) as an additive and sorbitan monostearate (Span 60) as a surfactant. Morphology, rheology, and tribology tests were conducted. The addition of NDCt and Span 60 to pure POE as a base fluid showed elevated viscosity, lower value of coefficient friction (COF), and a remarkable decrease in the wear rate (WR). The presence of 0.6 wt% NDCt and 1.8 wt% Span 60 in POE (N2S4) decreased the COF value by 79% in comparison to POE. At room temperature, this N2S4 biolubricant sample showed a higher thermal conductivity by 4% and lower WR value by 49% compared to POE. This study introduced the preparation of the ecofriendly biolubricant filled with NDCt improving the tribology properties remarkably.

“…45 It was reported that CNC dispersions produced by sulfuric acid treatment form a lyotropic liquid crystalline (LLC) phase, which was later identified as a chiral nematic phase in aqueous dispersions. 44,46,47 Cellulose and its derivatives', specifically CNCs, mechanical properties improve stiffness and strength of polymer composites promoting the creation of novel polymer nanocomposites and lubricants 48,49 or improving shape memory effects of polymer matrices. 50 In addition to synthetic polymers, chemically modified cellulose derivatives such as cellulose acetate, hydroxypropyl cellulose, and carboxymethyl cellulose have been used as additives for functional biomaterials to create films, membranes, electrospun into nanofibers 51 as well as formed into aerogel films, 52 hydrogels, 53 and three-dimensional porous foams.…”

This article reports tribological studies of piston ring/cylinder liner tribo-contact to evaluate the scuffing failure under dry sliding conditions and its minimization with mild extreme pressure lubrication. The tribological conjugation tested employs a piston ring of SAE9254 grade steel substrate with plasma-sprayed chromium coating of 42 µm and ISO R185220 grade gray cast iron cylinder liner. A conformal, cylinder inscribed in cylindrical cavity contact was ensured to simulate actual dead center reciprocating between piston ring–cylinder liner interface. Tribotests were conducted under dry sliding, simulating lubrication starvation and sliding in extreme pressure additivation blend at a temperature of 200 °C with 10 mm stroke length and reciprocating velocity of 0.2 m s–1. The friction characteristics of the piston ring and cylinder liner samples in cited test conditions were studied as a function of load and continuously monitored throughout the tests. Optimal profilometry was employed for evaluating wear attributes. For surface morphology and allied surface characterization, energy-dispersive X-ray spectroscopy integrated scanning electron microscopy was used. For tribo-chemical interactions and film formation, the tribo-surfaces were further investigated with Raman spectroscopy. ASTM E-384 standard Vickers indentation microhardness and its precedence to tribological characteristics were evaluated. The extreme pressure lubrication is intended to potentially improve the scuffing résistance and optimization of coating material in achieving superior tribological characteristics. Superior lubricity, scuffing resistance and enhanced load-bearing capacity attributes were manifested by EP-PAO10 blend lubrication contrasting the surface deteriorations and scuffing failure ascribed to dry sliding.
