Sažetak
This paper presents results of the structure analysis and tribological testing of a-C:H type diamond-like carbon (DLC) coatings produced by the Plasma Assisted Chemical Vapour Deposition (PACVD) technology on CoCrMo specimens. The DLC coating structure was studied by observing the surface topography using a scanning electron microscope (SEM) in the SE and STEM modes and a profilometer. Raman spectroscopy provided information on hybridized covalent bonds. The structural analysis involved observing the cross-sections of the coatings using a scanning electron microscope (SEM) with an energy dispersive spectrometer (EDS) to determine the concentration and distribution of the constituent elements in the coating. Wear resistance was studied by applying a T-17 pin-on-plate tribological system: a polymeric pin made of ultra-high-molecular-weight polyethylene (UHMWPE) and a CoCrMo plate with a DLC coating. The testing was conducted under friction conditions using Ringer’s solution as a lubricant. The test results showed that the application of DLC coatings definitely improves the serviceability of a surface.
