Abstract
The molecular dynamics analysis and experimental investigation of thin film lubrication of silicon nitride (Si3N4) and bearing steel(GCr15) under the n-hexadecane-based lubricant were studied. A molecular dynamics method was used to establish a molecular model with Materials Studio7.0 software. Forcite module for Geometry Optimization, Dynamics and Confined Shear in three steps. The effects of pressure and velocity on lubrication properties such as van der Waals energy and shear stress of film lubrication were explored. The Rtec friction and wear tester was used to test the Si3N4-GCr15 friction pair with the change of speed and load.
