Sažetak
The paper presents the results of DLC coating of produced by the method of physical vapor deposition (PVD) on the titanium alloy for biomedical applications. Surface morphology and elemental composition were determined with the use of Scanning electron microscopy (SEM)/ Energy dispersive spectroscopy (EDS). Hardness was determined by instrumental indentation. Tribological tests were carried out under technically dry friction and friction with lubrication of Ringer’s solution. The DLC”s are characterized by high hardness (increased by an 4-fold) and anti-wear properties. In the case of technically dry friction and in the case of Ringer’s solution, the coefficient of friction decreased by an 5-fold compared to the results obtained for substrate.
