%X In this work, some results are presented concerning the studies of friction coefficient distribution in     diamond-like-carbon (DLC) and molybdenum disulfide (MoS2) thin films stored in atmosphere environment. Tribological nanoscale analysis using Lateral Force Microscopy (LFM) were performed. Experiments aimed at establishing the tribological properties of sputtered DLC and MoS2 thin films. For friction measurements the LFM technique requires lateral movement of the Atomic Force Microscopy (AFM) tip in contact with a surface. The lateral force acts on the pyramidal tip attached to the end of the cantilever, due to friction or viscous forces, resulting in the cantilever measurable torsion and deflection related to friction's magnitude. The relationship among data from friction coefficient distribution, surface composition and crystal structure for DLC and MoS2 are compared and are presented for the first time. Auxiliary characterization techniques as Raman scattering spectroscopy (RSS), and X-ray photoelectron spectroscopy (XPS) for both DLC and MoS2 thin films are also presented.
