“…Pongamia and Neem oils showed better wear prevention behavior with HNTs and GNPs respectively [16,17]. Also, when the evaluation of GNPs inculcated Mahua oil was done for WPC, 0.25GMO sample showed supreme wear preventive behavior concerning other GNPs blended Mahua oil samples [32]. In the present work, the flashpoint, fire point, and viscosity tests were conducted only for 0.25GMO and compared with pure mahua oil (0GMO).…”

The tribological investigation was performed to seek the role of graphene nanoplatelets (GNPs) in enhancing the physico-tribological properties of mahua oil. The flashpoint, fire point, viscosity, wear preventive characteristics (WPC) and extreme pressure characteristics (EPC) were conducted following the governing standards. A substantial decrement of 17% in the coefficient of friction, 15.15% in wear scar diameter was observed upon blending the 0.25 wt.% GNPs with mahua oil. The WPC morphology on the steel balls portrayed the micro tracks. The EPC investigation presented 1 wt. % GNPs blended mahua oil with the augmented outcome of 7.7% and this was portrayed to be the best GNPs loading in weld load perspective. However, at 0.1 wt.% of GNPs loading was identified as the best loading with a wear point of view. The morphology of EPC revealed severe abrasion and steel balls were exposed to very high temperatures and have undergone metal squeeze out from the contact surface. This article also discusses the different wear regimes and corresponding wear phenomena in four-ball tribology testing with the aid of micrographs. RECEIVED

“…It is to be noted that pure bio-oils have poor oxidative stability and thermal resistance [3,4]. Sulfide and phosphide ions are present in synthetic oils; these ions help a lot in reducing wear scar diameter because of their repulsive action on the surfaces leading to the development of a thin protective film on the contact interfaces [5]. However, bio-oils do not contain these hydroxyl RESEARCH ions, hence an additive containing such ions are a preferable choice for blending with bio-oils.…”

In today’s paradigm petroleum and petro-based chemical products are being extracted and consumed at a substantial rate, proving to be hazardous and detrimental to the earth. Bio based resources are environmentally friendly, energy efficient, economical, and proved to be an alternative to the present mineral oils. This paper documents the research on naturally available mahua seed oil for bio-lubrication, its flash point and fire point, tribological properties namely coefficient of friction and wear scar diameter have been modified by the addition of zinc oxide (ZnO) nanoparticles in different concentrations by weight percentage (0.25, 0.50, 0.75, and 1.0). four-ball tester was used according to ASTMD-4172 standards (60 min under 40 kg running at 1200 rpm). Probe ultrasonicator was used for particle dispersion. It was found that 0.75 wt. % loading of ZnO in mahua oil resulted in a 57.14% drop of coefficient of friction, but a slight increase in the wear scar diameter of 30.60% was observed.

“…Even mahua oil which is chemically known to be Madhuca-indica is known to possess better lubrication characteristics. Suresha et al comprehensively evaluated the tribological behavior of mahua oil [15]. Many researchers noted that enhanced lubrication capability with reduced wear volume was observed with Mahua oil.…”

The scrutinized investigation of tribological performance of castormahua oil blends was comprehensively studied in comparison to SAE 20W40. Better miscibility and the negligible difference in density is the prime motive for the formulation of castor-mahua oil blend. Ten different blends are assimilated in the current investigation, and two better blends are utilized for further investigations of speed variations along with pure castor oil (B0) for the reference. The effect of speed variation of 1200 rpm, 900 rpm, 600 rpm, and 300 rpm were incorporated for better blends obtained in the inquiry. Blends B2(75 wt% of castor and 25 wt% of mahua oil) and B5(50 wt% of castor and 50 wt% of Mahua) showed extremely better tribological performance with 26.19% and 32.16% diminishment in coefficient of friction (COF), respectively, in comparison to SAE20W40. The variation of wear rate with speed and surface morphology of the balls are analyzed in the research work. The effect of vibration on the tribological parameters is investigated with an accelerometer equipment. All the results obtained from the research inquiry demonstrate the fact that castor mahua oil blends are promising and potential replacements for conventional synthetic oils.
