Tribological characteristics of titanium nitride and titanium carbonitride multilayer films

Sputter deposited NbCxNy films: Effect of nitrogen content on structure and mechanical and tribological properties

“…It is envisioned that the ternary NbC x N y will combine the good wear resistance and lubricious properties of NbN and NbC, respectively, and hence outperform both components as a lubricious wear protective coating. Similar advantages in ternary alloys have been reported, for example, for the solid solution TiC x N y compound deposited by cathodic arc ion plating, which outperforms TiN in tribological applications due to its higher hardness and decreased friction and wear associated with carbon incorporation [15]. It addition, CrC x N y coatings produced by evaporation in a thermionic-arc ionplating apparatus at 450°C show a higher corrosion resistance than CrN coatings [16], and MoC x N y films deposited by reactive directcurrent magnetron sputtering have a higher hardness than both MoC and MoN films [17].…”

Dry Sliding Wear Model of Nanometer Scale Multilayered TiN/CrN PVD Hard Coatings

“…For these authors, the explanation lies in the cracks propagation, hindered by each interface between layers, necessarily numerous in the case of multilayers. Other interpretations of wear resistance enhancement afforded to superlattices can be found in the literature: a reduction of adhesive wear [22], an effect of the sequence of the different nitrides layer [23] or the formation of a tribo-film lowering the friction coefficient and therefore wear rate [24].…”

Epitaxial NbC N1−(001) layers: Growth, mechanical properties, and electrical resistivity

“…Ternary transition-metal carbonitride coatings have gained increased interest in recent years, because their mechanical and tribological properties can outperform those of the binary nitride and carbide coatings [25][26][27][28][29][30][31][32]. For example, the solid solution TiC x N y compound deposited by cathodic arc ion plating exhibits a lower friction and wear and a higher hardness than TiN, and is therefore promising for tribological applications [25].…”
