“…During the rheology characterization of canola oilbased lubricants, a challenge was faced: Why does the elastic component G 0 appear at some times and disappear at other times? After investigations that eliminated the possibilities of errors and impurity effects, we concluded that the tested bio-lubricants behaved like liquid crystals; 25 then, the relationships between time, gap size, and substrate were determined. Figure 1 shows the growth of the elastic component with time.…”

The rheological behavior of a canola oil-based bio-lubricant was correlated with its surface activities using a rotary rheometer. The experiments on the gap size, substrate, and surface conditions led to a consistent and conceivable assumption that the self-assembled monolayer was extended to a degree that was sufficient to make a significant change in the bulk properties. In parallel, the thermal behavior was also connected to the surface activities. Differential scanning calorimetry was used to measure what is thought to be the monolayer melting point without using a graphite substrate. Crystallization points were measured at relatively high temperatures. Tribological tests were conducted and explained based on the rheological and thermal findings. A scenario describing both the boundary and bulk regimes was hypothesized. Rheometry and thermal analysis techniques are promising because of the variety of variables that could be controlled, such as temperature, shear, time, gap and substrate. To the best of our knowledge, this is the first study using macroscopic rheology to study the surfactant activities of vegetable oil. The influence of substrate and gap size on rheological behavior could change the current standards for using rotary rheometers.

“…The flash point of vegetable oil is higher which relates less vapour pressure and volatility, also reduces hazards during usage [17]. Vegetable oil based lubricants can be operated at lower temperatures and possess high natural stability, a high viscosity index, and a low coefficient of friction [18]. On the other hand, vegetable oil possess low thermal and oxidation stability at high temperature [19].…”

Vegetable oils are found as the feasible alternative for conventional minerals oils. There has been many environmental and health issues which are spotted with the use of conventional cutting fluids. There has been a great demand for developing new environmentally friendly vegetable based cutting fluids to reduce these harmful effects. In this present study, vegetable based kapok oil is used as a cutting fluid during milling to study its consequences over other conventional oils. The process parameters such as spindle speed, depth of cut and feed rate were optimized with respect to the flank wear (Vb) and surface roughness (Ra) respectively with the use of central composite design in response surface methodology (RSM). Further an attempt has been made to monitor the tool condition by measuring the cutting force, vibration and sound pressure simultaneously. Three different tool conditions such as dull, fresh and working were analyzed and their consequences were also reported. Also, the performance of the kapok oil is compared with the palm oil and mineral oil (SAE 20W 40). The feed rate has the major contribution for surface roughness and flank wear. It is found that the cutting force (F), sound pressure (p) and vibration (V) increases with the tool wear.

Castor Oil-Based Nanolubricants: An Overview

Vegetable oils are very effective, economic and appealing option as compared to conventional lubricants due to their environment-friendly nature, sustainable behaviour and biodegradability. Castor oil, one of the promising non-edible vegetable oils with nanoparticle additives has the potential to serve as base lubricating oil. The benefit of using nanoparticles in base oils is their small size, which works as a roller on contacting surfaces and results in reducing the wear and friction more efficiently. The present review paper has been structured as follows. The first part of this technical article is designed to give a brief about vegetable oils as a lubricant with special reference to castor oil. The second part of the review paper describes the effects of nanoparticles especially molybdenum disulfide (MoS2) in different lubricating oils, especially in castor oil. Finally, the applications of nanolubricants and their future prospects are also discussed.
