Technical Abstract: Most tribological processes (e.g. metalworking), occur in the mixed film regime where the boundary and hydrodynamic properties of the oils play critical roles. In the work described here, the boundary and hydrodynamic properties of various biobased oils were evaluated. The oils were then investigated for their mixed film lubrication properties as a function of various tribological parameters such as: load, speed, temperature, viscosity, lubricant chemical structure, polarity and concentration. The effect of these parameters as well as boundary and hydrodynamic properties on mixed film results are analyzed and discussed.
