Abstract
A molecular dynamics simulation study has been conducted in order to point out the effect of steady shear and loading
pressure on lubricant thin films. The model used in these simulations is composed of two solid walls and PFPE-Z lubricant.
We apply steady shear by moving the walls in opposite directions while at the same time the upper wall exerts a constant
load. The lubricant’s properties are investigated focusing on the shear thinning phenomenon and friction law. The obtained
results could be used to improve computer hard disk systems..
