Modelling the influence of friction modifiers and anti-wear additives on friction in the mixed/boundary lubrication regime Prof. Ian Sherrington(UK),

Ⅰ. Summary
This research has developed a simple method for reliably estimating mixed/boundary friction in a lubricated contact using the contact Lamba Ratio. The method is summarized by a single equation which can be applied both for un-additivated lubricants, and lubricants containing ZDDP anti-wear additives. Work is ongoing to apply a modified version of the equation to lubricants containing friction modifiers. The proposed equation is in good agreement with experimental data and its application suggests that some traditionally used mixed/boundary friction models (such as that of Greenwood-Tripp) significantly underestimate the amount of mixed/boundary friction. As mixed/boundary friction in machines is expected to increase in the future (due to the use of lower viscosity lubricants) simple, reliable methods to estimate friction losses due to mixed/boundary friction will become of increased importance, and the equation developed in this research will help tribologists and engineers to estimate such losses more easily.
