Technical Abstract: Plant-based oils are preferred for the manufacture of lubricants mainly because they are based on abundantly available and renewable raw materials (e.g., soybeans) and also because they present benign environmental problems associated with their production, blending, use, and disposal. However, wide use of plant-based oils in lubrication has not been achieved due to the inferior quality (e.g., poor oxidative stability and low temperature behavior) of lubricants from plant-based oils. Overcoming this problem will require a thorough understanding of the tribochemistry of plant-based oils. In this paper, we discuss our recent investigation into the relationship between the chemistry of plant-based oils and its boundary friction properties.
