“…The factors, and their levels as mentioned, are specified in Table 5. The level range of each factor is selected based on a number of recent studies [12,14,[21][22][23][24]. The 25 given experiments were performed in a random continuity order to exclude any other incorporeal agents, which might contribute whatsoever to the friction force and wear rate.…”

Abstract:The object of this research is to investigate the tribological properties of glycerol lubricant with aluminum nanoparticles as an additive and sodium dodecyl sulfate (SDS) as the dispersive medium for iron to iron friction using a thrust collar tribotester. Meanwhile, the effects of different concentrations of aluminum nanoparticles, SDS, and deionized water in glycerol on tribology properties of iron to iron friction were studied. The experimental parameters were set up according to the Taguchi technique, their influence on the coefficient of friction (COF) and wear rate were examined by response surface methodology (RSM) and analysis of variance (ANOVA) methods. The analysis results were employed to optimize the parameters to obtain the best lubricant effects. The optimal combination of the parameters for both minimum COF and wear rate was found to be 0.6667 weight percent (wt %) of aluminum nanoparticles, 2 wt % of SDS, and 10 wt % of deionized water content of glycerol. The wear surface topography and the average roughness of the surface were also examined using a scanning electron microscope (SEM) and a Mitutoyo Surftest SJ-400 instrument. The results show that aluminum nanoparticles used as an additive in lubricant reduce the surface roughness of a collar remarkably. The energy dispersive spectrometer (EDS) was utilized to confirm the deposition of aluminum nanoparticles on the collar surface leading to decreased friction and wear.

Lignin, one of the most naturally abundant polymers, has been successfully incorporated into ethylene glycol (EG) and poly(ethylene glycol) (PEG) in this work and fortified lubricating properties were achieved in EG/lignin and PEG/lignin. The molecular interaction between lignin and EG (or PEG) has been revealed as hydrogen bonding, which serves as the dominating factor that determines the thermal, rheological, and tribological properties of the mixed systems of EG/lignin and PEG/lignin. The physicochemical properties of the mixed lubricants are tightly related to the state of internal hydrogen bonding (EG−EG, PEG−PEG, EG−lignin, PEG−lignin, and lignin−lignin) and are well correlated to their lubrication properties. Generally, larger lignin fractions lead to better lubricating performance in both EG and PEG systems. Lignin liquefaction in PEG has been addressed by catalytic degradation with the presence of sulfuric acid, which was then neutralized by triethanolamine for lubricant development. Lignin in PEG significantly improves the lubricating property at higher pressure conditions, where a wear reduction of 94.6% was observed. Lignin fortified EG and PEG based lubricants show outstanding noncorrosive characteristic to the mostly used metal materials such as aluminum and iron.

“…Water-based lubricants are widely used as the metalworking fluids with high fire-resistance, good storage stability, excellent cooling abilities, and low-cost [1][2][3]. In practical applications, ethylene glycol is usually mixed with water, which can increase the viscosity and lubricity of water, and decrease its freezing point.…”

A water-soluble lubricant additive (RSOPE) was prepared by esterification reaction using fatty acid from rubber seed oil. The RSOPE was added into water-ethylene glycol (W-EG) solution as lubricant additive. Dispersion stability and rheological properties were investigated. We used a four-ball tribotester to assess the lubrication performance of W-EG based fluid with the RSOPE additive. The stainless-steel surface was analyzed using scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). Good dispersion stability was observed in the RSOPE/W-EG solutions. Furthermore, non-Newtonian fluid behavior at low shear rates and Newtonian fluid behavior at high shear rates was exhibited. The addition of RSOPE into water-glycol reduced the friction coefficients (COF) and wear scar diameters (WSD). The maximum nonseizure loads (PB) increased from 98 N to 752 N and the W-EG solution with RSOPE had good corrosion resistance properties. Good tribological performances for W-EG solution with RSOPE were attributed to the boundary tribofilm composed of iron oxide, iron phosphide and so on.
