“…34 Shen and Wang demonstrated that the corrosion resistance of titanium was improved after the formation of a TiN compound layer via plasma treatment. 35 In this study, we inserted a TiN layer between the metal electrode and the PC 61 BM/C 60 layers in a perovskite photodiode. The results of energy-dispersive X-ray spectroscopy (EDS) show that TiN restrains the migration of Ag and internal ions (Pb 2+ , I − and Br − ).…”

“…Thus, the peaks at the binding energies of 456.50 and 462.05 eV were believed to come from the Ti-N-O bond in the TiN x O y compounds. Notably, some reports considered that the characteristic binding energies range of the TiN x O y compounds might overlap that of the TiN satellite, and the peaks of the TiN x O y compounds and satellite were sometimes fitted into a single peak [13][14][15]. In N 1 s core-level spectrum (figure 3(c)), the peaks at the binding energies of 397.18 and 394.60 eV corresponded to the N-Ti bond in the TiN and the N-O bond in the TiN x O y , respectively, while the peak at 399.73 eV could be interpreted as the satellite feature of the TiN.…”

The gas nitriding of Ti13Nb13Zr alloy was performed in a pure nitrogen atmosphere at 1200 °C with different holding times. The variations in the phase constituents, microstructure, and mechanical properties of the nitriding layer with depth were characterized by SEM, XRD, and nanoindentation. Depending on the phase distributions in depth, the nitriding layer could be sequentially divided into an external nitride layer mainly consisting of TiN, an internal nitride layer consisting of TiN, Ti2N and TiN0.3, and an N diffusion region consisting of TiN0.3. The mechanical properties were closely associated with the phase constituents, where the nanohardness of the internal nitride layer, internal nitride layer N diffusion region and substrate were about 17.126±0.399, 12.120±0.386, 5.627±1.080, and 3.632±0.116 GPa, respectively. In the nitriding process, the N diffusion region containing needle-like TiN0.3 precipitates formed in the initial nitriding stage, and then the precipitates were gradually converted to the external and internal nitride layers, whose thickness increased with the nitriding time. Furthermore, the influence of the alloying element redistribution on the N diffusion mechanism was discussed.

Ti6Al4V titanium alloys, with high specific strength and good biological compatibility with the human body, are ideal materials for medical surgical implants. However, Ti6Al4V titanium alloys are prone to corrosion in the human environment, which affects the service life of implants and harms human health. In this work, hollow cathode plasm source nitriding (HCPSN) was used to generate nitrided layers on the surfaces of Ti6Al4V titanium alloys to improve their corrosion resistance. Ti6Al4V titanium alloys were nitrided in NH3 at 510 °C for 0, 1, 2, and 4 h. The microstructure and phase composition of the Ti-N nitriding layer was characterized by high-resolution transmission electron microscopy, atomic force microscopy, scanning electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. This modified layer was identified to be composed of TiN, Ti2N, and α-Ti (N) phase. To study the corrosion properties of different phases, the nitriding 4 h samples were mechanically ground and polished to obtain the various surfaces of Ti2N and α-Ti (N) phases. The potentiodynamic polarization and electrochemical impedance measurements were conducted in Hank’s solution to characterize the corrosion resistance of Ti-N nitriding layers in the human environment. The relationship between corrosion resistance and the microstructure of the Ti-N nitriding layer was discussed. The new Ti-N nitriding layer that can improve corrosion resistance provides a broader prospect for applying Ti6Al4V titanium alloy in the medical field.
