Abstract
In order to estimate the friction and wear properties of diamond like carbon (DLC) films, ball on disk test, Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDS) and Micro Laser Raman spectroscopy are accomplished in this study. DLC films are deposited on high speed steel (SKH51) surface by Plasma Based Ion Implantation and Deposition (PBII&D). After the sliding, the wear surface is observed by SEM, EDS and Raman spectroscopy. As the results, obvious changes in the structure of the DLC films originating from the contact interface between the substrate and the indenter are observed. This will be caused by the graphitization of the DLC films. In addition, the carbon compounds and the solid solutions of carbon and iron including the substrate hardly influence on the Raman spectra even though with and without the sliding.
