“…The hazardous effects and rapid depletion of petroleum-based lubricants are driving the environmental legislation authorities to find its suitable replacement for industrial applications. 1 The petroleum-based lubricants are non-renewable with low biodegradability and high ecotoxicity. As a result, researchers have suggested the use of bio-oils as a suitable replacement for petroleum-based lubricants.…”

The paper aims to study the antiwear (AW) and extreme pressure (EP) properties of avocado oil mixed with zinc dialkyl dithiophosphate (ZDDP) in concentrations of 1% to 3% by weight for lubrication purposes. The AW and EP tests are conducted as per ASTM-4172 and ASTM-2783 standards respectively. Further, the rheological behavior of avocado oil mixed with ZDDP is determined for varying shear rates of 50 – 2000 s−1. The maximum improvement in the wear properties for avocado oil is equal to 39.8% at 1 wt.%. The load wear index of pure avocado oil increases from 32.6 to 80.3 at 3 wt.% ZDDP whereas, the weld point increases to 252 kgf at 3 wt.% ZDDP. The improvement in the antiwear and extreme pressure properties are attributed to the protective film formation on the tribopairs as characterized by SEM and EDX analysis. Also, the addition of ZDDP increases the viscosity of the oil at all concentrations and maintains the Newtonian behavior of oil.

“…Double bonds are the active sites for oxidation resulting in the thermal degradation of the oil. Consequently, the oils with high monounsaturated fatty acids are considered as most desirable candidates for lubrication purpose [5]. Jayadas et al [6] further conducted a comparative tribological study of coconut oil and mineral oil on a four-ball tester and reported an improvement in the coefficient of friction with a negative effect on wear rate as compared to the petroleum-based lubricant.…”

The paper focuses on studying the rheological properties of different vegetable oils mixed with TiO 2 nanoparticles. The rheological tests of vegetable oils are conducted on cone and plate geometry of Anton Paars rheometer (MCR-102). TiO 2 nanoparticles are added in 0.5 wt%, 1 wt% and 1.5 wt% concentration. The density of nanofluids is measured from 20-80 °C, and the viscosity of nanofluids is measured at temperatures of 40 °C, 70 °C and 100 °C. All the nanofluids depict Newtonian behaviour at different temperatures and are quantified by power law. The introduction of nanoparticles in the oils leads to the increase in viscosity with 1.5 wt% TiO 2 concentration displaying maximum increase in viscosity in all the bio-oils. The variation of viscosity with temperature, shear rate and particle volume fraction is observed, and the measured values of viscosity are correlated with the existing theoretical viscosity models.

“…Friction and wear are events that occur unexpectedly in engineering projects and waste is a contaminant that becomes an environmental problem. Thus, the addition of nanoparticle additives in vegetable oils becomes an important alternative to minimize these risks [20].…”

This work was based on a comparative analysis of the action of Tung and Jatropha Curcas emulsions as cutting fluids for a CGI gray cast iron, where machining parameters, tool wear and fluid efficiency were analyzed. The results that followed the Reichert Test, milling with TiN coated carbide inserts, weight loss and pins temperatures measurements for each fluid.Given the operating conditions, the main wear mechanism presented by CGI gray cast iron machining, using Tung and Jatropha emulsions as cutting fluid, was flank wear, with adherence to the flank surface and the tool outlet. Therefore, substrate peeling was observed followed by chipping and breaking of the cutting edges of the tool with higher incidence in machining with emulsified Tung fluid.The tool wear zone occurred mainly near the radius of the tool nose on the flank side, with plastic deformation independent of the cutting speed.
