We have used pulsed vacuum arc deposition to prepare TixCy films and multilayer structures of TixCy / diamondlike carbon (DLC) in a dual plasma source set-up. The composition of the monolithic films was controlled by varying the pulse duration of each plasma gun. During the deposition, a repetitively pulsed bias voltage was applied to the substrate in order to improve the adhesion to the substrate and between the individual layers. For the multilayers, the carbon and Ti guns were synchronously pulsed during deposition of the TixCy, and the Ti gun was not operated during the DLC deposition. Multilayers with different periodicities were synthesized. The deposited films were analyzed by various techniques including XPS, AES, TEM, EELS, and XRD to characterize the composition, bonding states, and microstructure. Special attention was given to the interface thickness in relation to the applied bias voltage. Tribological properties such as friction coefficient and wear resistance were measured, and correlated to the composition and microstructure of the films.
