In the past two decades, coatings of the Ti–Al–N ternary system have attracted considerable research and industrial interest. Nevertheless, the Ti–Al–N system still offers new interesting possibilities for coating developments such as the addition of low N contents to Ti–Al films in order to reach a good compromise between high hardness and a low friction coefficient. Ti–Al–N coatings with low ...

We show that the Bloch states in conduction band of SrTiO$_3$ arise from interplay between highly anisotropic hopping sub-bands derived Ti $t_{2g}$ orbitals and spin-orbit coupling mixes these orbitals. Because nearly flat-band characteristics for one principal axes, at sufficiently high doping become unstable with respect to electron interactions, resulting Mott-like singlet correlations. Thes...

The Al–Fe–Ti system has been assessed and the limiting binary systems are shortly reviewed. Based on a thorough review of the literature, isotherms at 800, 900, and 1000 °C have been re-evaluated and a provisional isotherm at 1200 °C is presented for the first time. The effect of alloying the binary phases with the third component is reviewed with regard to the ternary homogeneity ranges, cryst...

An arc-sprayed amorphous Al–Ti–Ni coating on S355 structural steel was processed by laser remelting (LR) at powers of 600, 800, and 1000 W. The surface-cross-sectional morphologies, chemical element distributions, and phase compositions of the as-obtained Al–Ti–Ni coatings were analyzed using a scanning electron microscope (SEM), energy-dispersive spectrometer (EDS), and X-ray diffractometer (X...
