Abstract: The influences of electric double layer on thin lubrication
film thickness and pressure are studied. With the modified Reynolds
equation, the film thickness and pressure of hydrodynamic lubrication
and elastohydrodynamic lubrication are numerically calculated. The
results show that the influence of electric double layer on the
lubrication film thickness is significant while the initial film is very
thin. The minimum film thickness will greatly increase if the electric
double layer is considered. The increase of the initial film thickness
will greatly weaken the effect of electric double layer. Electric double
layer will decrease the friction coefficient. These tendencies are still
applicable even if the materials of the friction pair are different.
Key words: Electric double layer Thin film thickness Pressure
