Abstract
Vegetable oils can offer important environmental advantages with respect to biodegradability and renewability, as well as good performances in different applications. In this work, the rheological and tribological properties of an industrial canola oil-based bio-lubricant were investigated. They were compared with the properties of a mineral hydraulic lubricant used for similar applications. The tribological performance of the lubricants was investigated using a four-ball test and a pin-on-disk setup, and the rheological behavior was studied using oscillatory rheometry. The tested bio-hydraulic oil exhibited excellent lubricity. Liquid crystal additives affected the viscoelasticity differently. Moreover, the added ionic liquid crystal improved the wear resistance of the bio-hydraulic oil, but the original lubricant preserved the lowest coefficient of friction.
