Tribo-mechanical properties of reactive magnetron sputtered transition metal carbide coatings

Lattice distortion and residual stress of a carbon‐doped TiZrN coating

“…However, titanium‐based nitride has relatively lower mechanical properties than cBN and diamond‐like carbon (DLC) coatings. To overcome this limitation, researches about improving the mechanical properties trough the change of the coating composition or residual stress control have been conducted recently . It has been reported that the hardness was improved by substituting Zr, a transition metal, into TiN, and ongoing efforts to identify the mechanism are being made.…”

“…To overcome this limitation, researches about improving the mechanical properties trough the change of the coating composition or residual stress control have been conducted recently. [6][7][8][9] It has been reported that the hardness was improved by substituting Zr, a transition metal, into TiN, [10][11][12] and ongoing efforts to identify the mechanism are being made. In addition, carbon doping studies on titanium-based nitride are attracting attention since the carbon is stably infiltrated and substituted in the TiN lattice, leading to improved mechanical properties.…”

Influence of Slight Pressure Variations on the Mechanical and Tribological Properties of Ti/TiAlV/TiAlVN Coatings Produced by Magnetron Sputtering

“…For instance, by including Zr, the material can improve its chemical stability and mechanical performance, increasing the hardness and the Young's modulus. Other option consists in including Al, forming compounds as TiAlN coatings that, compared to TiN coatings have exhibited a better wear resistance, high oxidation temperature and high binding force (Kumar, 2015). On the other hand, in the literature it was found that, by adding V to TiN, an improvement can be observed in the mechanical and tribological performance (Montero-Ocampo, 2015).…”

“…On the other hand, in the literature it was found that, by adding V to TiN, an improvement can be observed in the mechanical and tribological performance (Montero-Ocampo, 2015). Combining the last two options, adding Al and V, a better performance can be obtained, decreasing the coefficient of friction (COF) of the surface at higher temperatures (Kumar, 2015); for instance, including V to TiAlN and producing a TiAlVN solid solution, in a face-centered cubic (fcc) structure, a material that exhibits high hardness and Young's modulus can be obtained (Pfeiler-deutschmann, 2015). These conditions can decrease the COF in a 60% at high temperatures (Kumar, 2015).…”
