TL;DR: In this article, the effect of Cu nanoparticles on the tribological properties of attapulgite base grease was investigated, and it was found that the friction reduction ability and anti-wear property of the base grease can be improved with the addition of CU nanoparticles.
Abstract: This study investigated the effect of Cu nanoparticles on the tribological properties of attapulgite base grease. It was found that the friction reduction ability and antiwear property of the base grease can be improved with the addition of Cu nanoparticles. Under the lubrication of grease containing Cu nanoparticles, a smoother and more compact tribofilm was formed on the rubbing surface. The tribofilm is mainly composed of Cu, FeO, Fe2O3, FeOOH, CuO, and SiO. In addition, the content of iron oxides and silicate oxide formed in the tribofilm was increased by the introduction of Cu nanoparticles.

TL;DR: In this paper, a new conductive grease was synthesized using a nanometer powder, i.e., Sb doped SnO2 (ATO), as an additive.
Abstract: A new conductive grease was synthesized using a nanometer powder, i.e., Sb doped SnO2 (ATO), as an additive. The typical properties of this new conductive grease were investigated in detail. The results indicate that ATO can dramatically improve the dropping point and reduce contact resistance. The tribological properties of the new conductive grease were investigated using the MFT-R4000 reciprocating friction and wear tester. The tribol-test results indicate that ATO can dramatically improve the tribological properties of the grease. When the ATO concentration is 0.1wt%, the grease demonstrates the best friction reduction properties; when the concentration is 0.5wt%, the grease demonstrates the best anti-wear properties. The worn surfaces were observed and analyzed by scanning electron microscopy and energy-dispersive X-ray spectroscopy, and the friction mechanisms for the new conductive grease are proposed. The excellent tribological properties of the new conductive grease are attributed to the mechanical effect of ATO, and the film formed by Sn and Sb elements or metallic oxide deposited on worn surfaces during the friction process.

TL;DR: The analysis of the film thickness measurements was performed with three fresh and aged greases, their base and bled oils under a wide range of operating conditions using a ball-on-disc test rig with optical interferometry as discussed by the authors.
Abstract: Several film thickness measurements were performed with three fresh and aged lubricating greases, their base and bled oils under a wide range of operating conditions using a ball-on-disc test rig with optical interferometry. The analysis of the film thickness measurements is in agreement with the observations of several authors and adds some important aspects regarding separate film properties in EHL contacts. At full film lubrication and moderate to high speeds, the bled oil showed a similar behavior of its lubricating greases. At fully-flooded condition, low speeds and thin films, it was observed that the thickener lumps play a major role on film formation, overcoming the bled oil effects. A relationship between thickener type and film formation was evidenced. The same trends were observed under starved lubrication, where the thickener type that contributes the most to locally increase the film thickness follows the order of PP > Ca > Li. The aging process of the greases was shown to change their rheological response in different manners—softening or hardening—depending on the grease formulation. Grease aging increased the film thickness under fully-flooded and starved lubrication, regardless of the level of degradation.

Abstract: Environmentally friendly multipurpose grease formulation has been synthesized by using Jatropha vegetable residual oil with lithium soap and multifunctional additive. The thus obtained formulation was evaluated for its tribological performance on a four-ball tribo-tester. The anti-friction and anti-wear performance characteristics were evaluated using standard test methods. The biodegradability and toxicity of the base oil was assessed. The results indicate that the synthesized residual oil grease formulation shows superior tribological performance when compared to the commercial grease. On the basis of physico-chemical characterization and tribological performance the vegetable residual oil was found to have good potential for use as biodegradable multipurpose lubricating grease. In addition, the base oils are biodegradable and non toxic.

TL;DR: In this article, an experimental study of starvation and flow behavior in grease-lubricated elastohydrodynamic contact was conducted. But the authors did not consider the effect of the number of fingers on the track of the disk.
Abstract: This paper describes an experimental study of starvation and flow behavior in grease-lubricated elastohydrodynamic contact. Rolling tests were conducted with four grease samples with different thickeners and base oils in a conventional ball-on-disk test rig. The EHL central film thickness was determined with SLIM, the Spacer Layer Imaging Method, and grease flow around the conjunction and the flow pattern on the track of the disk specimen were observed with CCD cameras. The grease track included some thickener deposited on the track and a corrugated fingerlike flow pattern outward from the center of the track. It was found that the flow pattern varied with grease type and test conditions, and that the average interval between fingers decreased with the entrainment speed. At higher speeds, inlet starvation occurred and the finger pattern was deformed and gradually ruptured. The speed of the finger-loss was higher than the speed at which starvation started. It was also found that the starvation speed was greater with greases having lower apparent viscosity at lower shear rate and higher apparent viscosity at high shear rate. This implied that the replenishment and entrainment of the greases depended on the viscosity characteristics of the greases.

TL;DR: In this article, a model of free-surface flow of grease on a rotating disc was investigated in the form of a free surface flow of greaseprocessor, and experiments have been performed where the onset of flow and remaining grease have been studied varying the surface roughness, temperature and the centrifugal forces.
Abstract: Grease flow in grease-lubricated systems can often be qualified as free-surface flow. It occurs, for example, in rolling bearings after the churning phase or on open gears. Here only a fraction of the bearing or gearbox volume is filled with grease. Part of the grease is flowing in relatively thin layers induced by centrifugal forces caused by rotation of the various components. In this paper, a model problem is investigated in the form of a free-surface flow of grease on a rotating disc. Experiments have been performed where the onset of flow and remaining grease have been studied varying the surface roughness, temperature and the centrifugal forces. The experiments have been coupled to analytical models describing the flow and temperature distribution in the grease. It was found that the impact of surface roughness could be neglected. The flow is determined by the centrifugal forces and rheology of the grease. Temperature effects the rheology but also the oil separation creating low shear strength/low viscosity layers at the surface.

TL;DR: In this paper, a low-temperature lubricating grease composition and a preparation method for low-pressure abrasion resistance has been proposed, which can be used for breaking through the lubricating management concept of different grease using in winter and summer.
Abstract: The invention provides a low-temperature lubricating grease composition and a preparation method thereof. The composition is prepared from base oil, a thickening agent and an additive. The lubricating grease is prepared from a novel thickening agent system and base oil with excellent low-temperature property, so that the lubricating grease has excellent low-temperature fluidity, corrosion and rust resistance and extreme-pressure abrasion resistance; since organic bentonite has a relatively good low-temperature rheological property and does not have phase transformation in the process of forming grease, the denseness of the lubricating grease is not remarkably influenced in temperature changes, the lubricating grease cannot be hardened at a low-temperature environment at -40 DEG C, and the pumping continuity can be ensured. The lubricating grease can be used for breaking through the lubricating management concept of different grease using in winter and summer, which is generally used by large-sized engineering machinery in 'Three-North' regions, so that innovation of universal application of the grease in winter and summer can be realized, and maintenance cost and labor intensity of clients can be reduced.
TL;DR: In this article, the effect of heat treatment on the tribological properties of lithium lubricating grease is discussed, and it is confirmed that the variation of physical entanglement, which was caused by a short heat treatment, would vary the tribologically properties of the lithium lubricating grease.
Abstract: Owing to the potential oxidation and thermal degradation of lithium lubricating grease when the grease is heated to improve its fluidity in the pumping process, fresh NLGI 3 lithium lubricating grease samples were heated to obtain experimental samples to simulate the static thermal degradation by using a drying oven. The microstructure and infrared spectra were studied by using field emission scanning electron microscopy (FESEM) and Fourier transform infrared spectroscopy (FTIR) techniques respectively. The rheological properties were estimated by a rotational rheometer and the tribological properties were evaluated on a four-ball testing machine. Finally, the action mechanisms of the effect of heat treatment on the tribological properties of lithium lubricating grease are discussed. The experimental results showed that the lithium lubricating grease samples exhibited better antifriction and antiwear properties after heat treatment at 120 °C, which is not obvious during 0–4 h, while the coefficient friction and extreme pressure progressively decreased during 4–24 h. Meanwhile, oxidative and thermal degradation do not proceed after heat treatment for 0–24 h according to the FESEM and FTIR results. Finally, it was confirmed that the variation of physical entanglement, which was caused by a short heat treatment, would vary the tribological properties of the lithium lubricating grease.
TL;DR: In this paper, a method for the production of paper with high strength and grease resistance was developed, where filter paper was impregnated by an aqueous solution of zinc chloride at a fixed temperature for several seconds.
Abstract: A method for the production of paper with high strength and grease resistance was developed. Filter paper was impregnated by an aqueous solution of zinc chloride at a fixed temperature for several seconds. Swelling and partial dissolution of the cellulose fibers resulted in strong and compact paper. Various influencing factors were investigated in an attempt to improve the grease resistance of the paper. In addition, the structural properties of the zinc chloride-treated paper were investigated using a Fourier transform infrared (FT-IR) spectrometer, X-ray diffraction (XRD), and a scanning electron microscope (SEM). Paper treated in this manner was completely grease resistant, had greater stretch, and twice as high tensile strength when compared with untreated paper, while its burst strength more than doubled. Paper treated according to this method had the skeleton of un-dissolved cellulose fibers and the matrix of gelled cellulose. The cellulose of the paper was not chemically modified during this process.
TL;DR: In this paper, the relationship between microstructure and tribological performance of the lubricating greases was investigated via a rheological method, which indicated that the fiber dimension determined the level of physical entanglement and the evolution of fiber network in the friction process, further influencing the final lubricity.
Abstract: By controlling the heat-treatment process, three types of lithium greases with different thickener fiber morphologies were synthesized via the saponification reaction. With increasing the cooling rate, the dimension of the thickener fiber decreased. The relationship between microstructure and tribological performance of the lubricating greases was investigated via a rheological method. The results indicated that the fiber dimension determined the level of physical entanglement and the evolution of fiber network in the friction process, further influencing the final lubricity. The grease with the large fiber dimension displayed good tribological performance under low frequency and high load conditions due to its large-scale strongly crosslinked structure. In addition, the grease with the small fiber dimension yielded a low level of fiber physical entanglements and displayed low structure strength and fast response in the rheological test. It could obviously improve the tribological performance under high frequency conditions. Through tuning the microstructure of the thickener fiber according to the lubricating conditions, the tribological performance could be obviously improved.

The ILs have good solution in poly(ethylene glycol-ran-propylene glycol) monobutyl ether (PAG) and thus can be used as a base oil for preparing grease for steel–steel contacts. The electrical conductive properties of the grease prepared with the mixed oil of PAG plus ILs were evaluated using the DDSJ-308A conductivity tester, GEST-121 volume surface resistance tester, and HLY-200A circuit resistance tester.

TL;DR: The results indicated that fat, oil, and grease is feasible to produce methane and the ideal substrate to inoculum ratio range of 0.5–1.0 was determined, which corresponds to 81–89% methane production.
Abstract: Anaerobic digestion is one of the potential methods widely applied for organic waste recovery to produce biogas. In this study, biodegradability of fat, oil, and grease was tested in biochemical methane potential assays and the effects of substrate to inoculum ratio ranging from 0.2–4.0 were determined. The results indicated that fat, oil, and grease is feasible to produce methane (670 mL CH4 gVS−1) and the ideal substrate to inoculum ratio range of 0.5–1.0 was determined. After 60 days of experiments, maximum methane yield for the ideal ratio was 603–741 mLgVS−1, which corresponds to 81–89% methane production. Increasing substrate to inoculum ratio showed a lag phase phenomena where methane yield may be decreased initially or started slowly, thus delaying the entire digestion process. With a higher substrate to inoculum ratio (2.0–4.0), methane yield was recorded lower than 60% and the highest methane production was 250.2 mLgVS−1.

TL;DR: In this article, European beeswax was used as a thickening material for the preparation of lubricating greases and two mineral oils were used as base oils to evaluate the consistency, dropping point temperature, and tribological properties of the prepared greases compared with conventional soap-thickened greases.
Abstract: Environmentally friendly lubricants are preferred in many applications where groundwater or soil pollution is possible. The main purpose of the current study was to evaluate the possibility of beeswax use as a thickener for lubricating greases. European beeswax was used as a thickening material for the preparation of lubricating greases. Rapeseed oil and two mineral oils were used as base oils. The consistency, dropping point temperature, and tribological properties of the prepared lubricating greases were investigated and compared with conventional soap-thickened greases. The prepared greases exhibited good tribological properties, especially the rapeseed-oil-based grease. However, tribological properties of conventional lubricating grease were superior to prepared ones. The weakness of the prepared lubricating greases is their narrow working temperature range. However, the beeswax together with rapeseed oil has great potential in the production of environmentally friendly, completely renewable lubricating greases. Copyright © 2014 John Wiley & Sons, Ltd.
