Abstract
X-ray diffraction measurements on titanium nitride coatings prepared by the physical vapour deposition method in a magnetron were performed. The peak positions, intensities, integral breadths and shape parameters have been determined and related to layer characteristics (lattice parameters, texture, strain and domain size) for several sets of samples deposited under various conditions and also with different film thicknesses. In addition, the stress was measured by the X-ray method. A strong dependence of the lattice parameters and X-ray line broadening on the crystallographic direction as well as on the line asymmetry appeared systematically for certain deposition conditions. Interpretation of this effect is not clear and therefore detailed results are presented together with some possible reasons for such an anisotropy.
