| Abstract: | In this paper the chemical structure of solid lubrication film formed on the specimen surface under different lubrication regime was analyzed using Scanning Electron Microprobe (SEM), Wavelength Dispersion Spectroscopy (WDS), Scanning Auger Microprobe (SAM) and X-rays Photoelectron Spectroscopy (XPS). It was observed that there was a defined corresponding relation between the transition of lubrication regime and the chemical structure of solid lubrication film. The experimental results show that a mixed solid lubrication film-containing graphite and MoS2 is formed on the surface under the boundary lubrication regime, which result in a good tribology behaviour of Mo/Cr2O3 system at high temperature. |
