“…Figure 5(a,b) shows the XPS spectra of Ti under different conditions. The binding energies of 455.3 and 458.0 eV correspond to TiN [26] and TiO 2 [27], respectively. According to the XPS results, the TiN phase transformed into TiO 2 under argon; by contrast, the coating retained the TiN phase under nitrogen, even when the annealing temperature reached 1000°C.…”

TiAlSiN coatings were deposited on Si substrates by ion beam-assisted deposition. The oxidation resistance and mechanism of TiAlSiN at 800°C, 900°C, and 1000°C under a nitrogen atmosphere were discussed and compared with those of TiAlSiN under argon and air atmospheres. The microstructure, bonding characteristics, and phase transition of the coatings were systematically investigated. The results indicated that nitrogen atmosphere effectively inhibited oxidation of the TiAlSiN coatings. The key reason for this improvement was that nitrogen maintained Ti-N and Si-N chemical bonds, and a dense Al 2 O 3 layer was much more easily generated under the nitrogen atmosphere. We used first-principles calculations to investigate the electronic structures and bonding characteristics of TiAlSiN in this work.

“…In view of the abundance of devices meeting the criterion above, fretting wear commonly occurs in many branches of science and technology. Wear traces were noted, for example, on a truck frame [21], airplane elements [22][23], rail vehicle elements [24] and orthopaedic implants [25][26].…”

Subject to the analysis was a tribological kinematic pair consisting of shaft and sleeve, both made of C45 steel. The elements were joined by pressing with the 0.02 mm tolerance. The shaft was subjected to the finishing and strengthening treatment consisting in induction hardening. The tribological kinematic pair made in such way was tested on a fatigue testing machine, which permitted obtaining a rotational bending moment. Macroscopic investigations of the unhardened shaft demonstrated, on the shaft surface, the traces of fretting wear in the form of a ring of the uniform width comprising the entire axle seat circumference. Based on the test results, it may be concluded that the use of the shaft induction hardening process has caused the reduction of fretting wear development compared to shafts without additional treatment. In this case, Wear traces in the form of small diameter ring comprising the entire shaft circumference are observed on one side of the shaft axle seat.
