Abstract :
The thermal stability of lubricant films under various temperatures was examined by means of molecular dynamics simulation. The result showed that the lubricant desorption is favored over decomposition and is the major cause of lubricant failure on the disk surface. The surface tension of lubricant was calculated and analyzed as well.
