Interpretive Summary:

Technical Abstract: Seed oil is a potential replacement for mineral oil as a base fluid for making grease. The advantages of using products based on seed oils are their eco-friendly and non-toxic nature. This work focuses on the development of soy oil-based lithium grease using a variety of fatty acid component to obtain the thickener (metal soap) structure. It has been observed that the physical and chemical properties of grease are largely based on the soap thickener fiber micro-structure. A transmission electron microscope methodology was developed to study the nature and structure of soap dispersoid in grease matrix. Tribochemical and oxidation studies were designed and the data obtained show excellent anti-wear/friction and oxidation properties of soy-based greases.
