Description	Tribologické vlastnosti povlaků DLC/WC byly měřeny pomocí pin-on-disc zařízení THT Tribometer v rozsahu od pokojové teploty do 500 °C. Vlastnosti byly vyhodnoceny s ohledem na míru opotřebení protikusu a povlaku, koeficient tření a analýzu otěrových částic. Byla sledována záběhová fáze ocelové kuličky při tření proti povlaku DLC měřením opotřebení protikusu in situ. Výsledky ukázaly, že objem opotřebení zůstává přibližně konstantní v oblasti počtu cyklů 1500 až 5000. Tento jev byl způsoben pouze poklesem kontaktního tlaku, ke změně módu opotřebení nedochází, protože průběh koeficientu tření je ustálený. Tření a opotřebení povlaků DLC poukázalo na omezené možnosti využití v praktických aplikacích, zejména v prostředí se zvýšenou teplotou. (cs) Tribological properties of nanostructural DLC/WC coatings were measured with a high temperature pin-on-disc CSM Tribometer in the range from room temperature (RT) up to 500 °C. The tribological performance was evaluated with respect to the wear rates of balls and coatings, friction coefficient and wear debris analysis. The running-in phenomenon of steel ball sliding against DLC coating was studied by sequential in situ measurements of ball wear rate. The wear volume was almost constant from number of cycles of 1500 to 5000. This phenomenon was caused by lowering of contact pressure and couldn't be caused by changing of wear mode; the measured friction coefficient showed no fluctuation at 1500 cycles. Friction and wear characteristics described in this study showed their limitations of DLC applicability.
