EVALUATION OF THE PROPERTIES OF DIAMOND-LIKE CARBON COATINGS LUBRICATED WITH IONIC LIQUIDS
Journal Title: Tribologia - Year 2017, Vol 275, Issue 5
Abstract
The purpose of the study was to evaluate the properties of DLC coatings with ionic liquids used as lubricants. The type a-C: H DLC coatings were deposited onto the 100Cr6 steel substrate by PVD. The surface topography of the DLC coatings was studied with a Bruker's Dimension Icon® Atomic Force Microscope (AFM), and surface morphology testing, cross section and chemical composition analyses were performed using the Jeol JSM-7100F scanning electron microscope, equipped with an EDS microanalyzer. Surface geometry measurements prior to and after tribological tests were performed on a Taylor Hobson's Talysurf CCI contactless optical profilometer. The tribological tests were carried out on an Anton Paar TRB tribotester under technically dry and lubricated friction with an ionic liquid, 1-Butyl-3-methylimidazolium tetrafluoroborate. The results show that DLC coatings and ionic liquids can significantly reduce resistance to motion.
