What is it about?

Conventional lubricants used in machinery are derived from mineral oils. High cost and environmental issues associated with mineral oils forced researchers to strive for the development of eco-friendly lubricants. Vegetable oils are seen to be contrasting options to mineral oils for lubricant development on account of their innate specialised properties and their capacity towards biodegradability together with reduced cost. The objective of this work is to evaluate the viscosity and tribological efficiency of blended vegetable oils for developing new biodegradable vegetable oil lubricants that can substitute commercial mineral oils (e.g. SAE20W40).

Why is it important?

The developed blended vegetable oil based nanolubricant exhibits high VI (∼180), high flash and fire point, and relatively moderate thermal stability as per the requirements of commercial mineral oils. Thus blended vegetable oil based nanolubricant can be used as a promising biodegradable lubricant for many applications like two-stroke engine oil, hydraulic fluid, gear oil, textile lubricant etc.


I hope this research article will be very useful for the people doing research in bio-lubricants, which is a potential area in influencing the environmental friendliness.
