The evaluation of lubricant properties and environmental effect of bio-lubricant developed from rice bran oil

摘要

This paper deals with the comparison of lubricant properties and environmental effect of newly developed bio-lubricant based on rice bran oil. The various lubricant properties like rheological, tribological, thermal properties, oxidative stability, corrosive stability, biodegradability and toxicity of the formulated oil have been evaluated and compared with a commercially available lubricant SAE 20W40. The formulated oil from rice bran oil is found to be highly biodegradable, less corrosive and non-toxic. Even though the coefficient of friction of the formulated oil is less compared to SAE 20W40, the wear scar diameter is slightly high compared to SAE 20W40.
