The present work is aimed at determining the conditions for which synthesis of coatings composed of solid solution TiBN is possible using cathodic arc evaporation, a member of the physical vapor deposition family of coating techniques. Such coatings are interesting from a machining point of view because they have previously been shown to exhibit excellent tribological properties at elevated temperatures. A combinatorial approach was employed, in which several coatings with differing B-content were grown at once. Several such coating experiments were performed with varying process parameters, e.g. gas mixture composition and temperature. Analysis of the deposited coatings was carried out using X-ray powder diffraction, scanning electron microscopy and wavelength dispersive X-ray spectroscopy to determine the crystal structure, morphology and chemical composition. The results of these measurements are discussed at length.
