![]() Based on the powder sample, the XRD data of the pure fcc-Ti 1− xAl xN phase were measured and the lattice constant of the fcc-Ti 1− xAl xN phase in the powder was determined to be a = 0.407168 nm. The stoichiometric coefficient of fcc-Ti 1− xAl xN was measured on a flake containing only the fcc phase. The powder consisted of 88% fcc-Ti 1− xAl xN. Following the Ti 1− xAl xN coating, a flake of the free-standing layer and the powder were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), selected area electron diffraction and high-resolution transmission electron microscopy (SAED–HRTEM), wavelength dispersive X-ray spectroscopy (WDS) and energy dispersive X-ray spectroscopy (EDS). A powder was produced using the major part of the flakes of the free-standing Ti 1− xAl xN layer. The steel foil was etched and flakes of a free-standing Ti 1− xAl xN layer were obtained of which a part consisted of a pure fcc phase. In the first step, a 10 µm thick Ti 1− xAl xN coating was deposited on steel foil and on cemented carbide inserts by CVD. In this work, an aluminum-rich fcc-Ti 1− xAl xN powder was prepared and, for the first time, a powder diffraction file of fcc-Ti 1− xAl xN was determined experimentally. However, there exists no JCPDF card of fcc-Ti 1− xAl xN for the XRD analysis of such coatings based on experimental data. Fcc-Ti 1− xAl xN-based coatings obtained by Physical Vapor Deposition (PVD) or Chemical Vapor Deposition (CVD) are widely used as wear-resistant coatings.
