- ItemEvaluation of Changes In The Utility Properties of A Base Material After The Application of Thin Coatings Of Wc/C, Tic/C and A Carbon-Based Coating: Ta-C(Tanger, Ltd., 2019-01-01) Kavánová Anna; Bakalova Totka; Svobodová Lucie; Kejzlar Pavel; Louda PetrTribological coatings are mainly used to reduce adhesive wear, which often leads to the seizure or the formation of cold welds. The low coefficient of friction and good sliding properties make it ideal for applications with low lubrication or even dry running. The result is an ideal way to reduce surface fatigue and tribo-oxidation. Tribological coatings have good sliding properties, a low coefficient of friction and low adhesive wear. Thin layers of WC/C and TiC/C of the MeC/a-C: H coating group were deposited onto the surface of ISO 683/11- 70 steel. The third tribological coating deposited on the same substrate was a ta-C coating - a tetrahedral amorphous layer (stoichiometry: sp3 bonds > 50%). Tribological measurements were performed at a load of 10 N, a rotational speed of 60 rpm, and with a counterpart of ceramic material Al2O3.
