Pulsed DC titanium nitride coatings for improved tribological performance and tool life

Composition and structure–property relationship of low friction, wear resistant TiN–MoSx composite coating deposited by pulsed closed-field unbalanced magnetron sputtering

“…In addition to this, when the substrate bias is also pulsed, the plasma field due to oscillating nature becomes more energetic, causing improvement in ion current density drawn at the substrate [11]. The PMS process, therefore, can have a significant beneficial impact on the structure and properties of PVD coatings as reviewed in different literature [10,12,13].…”

Photocatalytic activities of N-doped nano-titanias and titanium nitride

“…[33][34][35] In general, phase-pure TiN tends to be made under more severe conditions than low level Ndoped titania, e.g. reactions require higher temperatures, involve high-energy processes or are carried out in vacuo (to eliminate reoxidation).…”

Investigation of the adhesion of NbN coatings deposited by pulsed dc reactive magnetron sputtering using scratch tests

“…In addition, the highenergy atoms, with their greater mobility to find the low-energy wells on the surface, can improve the adhesion characteristics. [30][31][32][33] Despite the fact that the critical load for the coatings can be determined at the end of the test under a progressive load, it was observed that the coatings were damaged at load values that were below the critical load determined from progressive scratch tests, and that this was due to the relative movements. Thus, one of the most suitable methods for evaluating the coatings friction fatigue and wear strength under elastic loadings is to conduct a MPST.…”
