The Tribological Characteristics of TiCN Coating at Elevated Temperatures

Original language description

The tribological behaviour of TiCN coating prepared by unbalanced magnetron sputtering is studied in this work. The substrates made from austenitic steel were coated by TiCN coatings during one deposition. The measurements were provided by high temperature tribometer. The steel balls and the Si3N4 ceramic balls were used as counter-parts. The wear tracks were examined by optical methods and SEM. The surface oxidation at elevated temperatures and profile elements composition of the wear track were also measured. The experiments have shown considerable dependency of TiCN tribological parameters on temperature. Rise in temperature increased both friction coefficient and the wear rate of the coating in case of 100Cr6 balls. The main wear mechanism was a mild wear at temperatures up to 200 oC; fracture and delamination were dominating wear mechanisms at temperatures from 300 to 500 oC.

Tribologické chování TiCN za vyšších teplot

Czech description

Studie se zabývá tribologickým chováním TiCN v teplotním rozsahu 20-500 oC. Otěrové zkoušky byly provedeny na tribometru pin-on-disc, přičemž jako protikus byly použity ocelové kuličky 100Cr6 a rovněž Si3N4. Růst teploty se projevil nárustem třecího součinitele a otěru vrstvy i kuličky v případě 100Cr6; otěr keramické kuličky byl zanedbatelný. Hlavním otěrovým mechanismem byl "mild wear" při teplotách do 200 oC, při vyšších teplotách pak delaminace vrstvy.
