Improvement of the electrochemical behavior of steel surfaces using a TiN[BCN/BN]n/c-BN multilayer system

A Practical Application of X-Ray Spectroscopy in Ti-Al-N and Cr-Al-N Thin Films

“…According to the literature (Tam et al, 2008;Kim et al, 2002) for the Ti2p1/2 peak, the first one (463.5 eV) and the second one (458.6 eV) can be assigned to Ti-O2 and Ti-N bonds. The appearance of the peak at 457.6 eV clearly shows that Ti has reacted with N; therefore, it can be assigned to Ti-N (Badrinarayanan et al, 1989;Moreno et al 2011). Fig.…”

“…The integral of O1s, N1s, Al2p3/2, and Cr2p3/2 spectra corrected by relevant sensitive factors can evaluate the concentrations of Cr, Al, and N elements in the Cr-Al-N films. The corresponding integral of the deconvoluted peaks can also be used to estimate the bond contents, which are described by the following equation (Moreno et al, 2011):…”

A non-destructive method for determination of thermal conductivity of YSZ coatings deposited on Si substrates

“…So, the bulk sample density is not analyzed by Archimedes method due to the simplicity of the Archimedes method to determine the density of a bulk sample, moreover, in this work the coating sample density have high consideration the conductivity response. Additionally, to determinate the total coating porosity of the YSZ, the ratio between the polarization resistance of the uncoated substrate and that of the coated substrate was used, according to the following equation [38,40,41]:…”

High temperature behavior of functional TiAlBSiN nanocomposite coatings

“…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.…”
