Abstract: A number of multicomponents, nanostructured coatings have been produced for a range of tribological applications. This paper will discuss four such nanocomposite coating systems: (i) Ti–Si–B–C–N; (ii) Cr–B–N; (iii) TiC–C and (iv) Cr–Al–N produced by Unbalanced Magnetron Sputtering (UBMS) in which the deposition parameters have been varied to control the structure and properties of the films. In each case, the coating system needs to exhibit a range of tribological properties to meet the required application, such as high wear resistance, low coefficient of friction, self-lubrication, high oxidation and/or corrosion resistance. In particular, the effect of the film chemistry, pulsing the magnetron and utilising a closed field configuration will be discussed as suitable control parameters in tailoring the structure and properties of the coatings to meet specific tribological applications.
