“…The combination of: corrosion resistance of AlN up to 1000°C [26,27], electric conductance and superior physicomechanical properties of both TiB 2 and TiSi 2 makes the high temperature composite ceramic AlN-TiB 2 -TiSi 2 a leading candidate that can meet the requirements for protective coatings for high temperature applications [28][29][30][31]. Bulk ceramics AlN-TiB 2 -TiSi 2 display superior physicomechanical and tribological properties up to 1450°C [32], additionally, Si and B are metalloids which are very effective in stabilizing amorphous phases.…”

This article reports on the thorough characterization of structural-phase transformation in amorphous TiAlBSiN coating after high temperature annealing at 900°C in ambient air. The influence of annealing on the tribomechanical behavior of the coating at nano and micro scale was also examined. The research included multiple experimental techniques, i.e. AFM, SEM, TEM, HR-TEM, EDS, XPS and Raman spectroscopy. Experiments showed that the amorphous phase of the TiAlBSiN coating undergoes a structural transformation, evidenced in the changes of parameters such as topological and chemical short-range order after the post-deposition annealing at 900°C in air. The observed structural transformation, leads to a phase separation with the formation of a three dimensional nc-TiAl 3 /a-SiBN(O) nanocomposite structure. The relative increase of hardness, reduced elastic modulus, H/Er ratio and H 2 /E 3 r ratio after high temperature treatment of TiAlBSiN coatings is also reported. The complex interdependency between chemistry, morphology and relative composition of the amorphous TiAlBSiN coating phase, during the high temperature treatment, with the respective change of the tribo-mechanical characteristics, are evidence of the improvement of the coating properties in response to the environmental conditions and high temperature. This work contributes particularly to the development and understanding of flexible nanocomposite protective coatings and their changes at high temperature of operation.

“…Coatings deposited via PVD based on nitrides (HfN [3], VN [4] and TiCN [5], provide high wear resistance, stability under high-service temperature, corrosion resistance, and low thermal conductivity; recently, interstitial nitrides like vanadium nitride (VN) and hafnium nitride (HfN) are being studied because of their interesting properties like high hardness, elastic modulus, low friction coefficient, wear and corrosion resistance, [6][7][8][9]. In recent years, multilayer systems based on nitride coatings like TiN/ZrN [10], TiN/VN, Hf/HfN and W/WN [11,12] have been deposited as multilayer systems. These systems have shown good results specifically related to improved mechanical properties and oxidation resistance, as compared to the single layer, e.g., CrAlN and TiAlN coatings [13,14].…”

“…The relative intensity of the peak K was determined by dead time corrections and a referent correction for the X-ray measured. So, before each quantitative analysis of an EDX spectrum, a manual background correction and an automated ZAF correction was carried out [19]. Thus, Table 1 shows the energy-dispersive X-ray spectroscopy (EDX) values of TiN and Al-Ti-N single layered, respectively, deposited with r.f.…”
