Evaluation of Solid Lubricants: Temperature Programmed Desorption of MoS2 on Molybdenum and of Ion-Implanted MoS2 on Molybdenum

Abstract

Thermal programmed desorption (TPD) is utilized in order to assess the lubricating properties of metal dichalcogenide films applied to a number of metal substrates. TPD spectra documenting desorption and decomposition products were analyzed for MoS2 burnished on molybdenum metal with and without subsequent 86 kV nitrogen ion implantation. Desorption order, rate, energy, and the pre- exponential of evolved lubricant and nitrogen species from the molybdenum substrates were determined. The surface chemistry of heated lubricant-substrate system was investigated by means of X-ray photoelectron spectroscopy (XPS). Keywords: Solid lubricants, Molybdenum disulfide, Mass spectrometry, Surface analysis, Thermal degradation, Thermal stability, X-ray photoelectron spectroscopy.
