“…The average friction coefficients vary between 0.7 and 0.9 at RT and between 0.9 and 1.0 at 500 and 700°C for the multilayer coatings, without any pronounced influence of the multilayer wavelength. This is comparable to those values reported earlier for the corresponding single-layers [4,6]. The wear coefficients determined by ball-on-disk testing against alumina balls at room temperature, 500 and 700°C can be seen in Fig.…”

“…The incorporation of V in the form of a TiN/VN multilayer or as solid solution Ti-Al-V-N coating led to potential low friction and enhanced wear behavior [1][2][3]. Additionally, it has been shown that V as a substitutional atom in the Ti 1 − x Al x N solid solution has a stabilizing effect for the face-centered cubic (fcc) structure, which is characterized by high hardness and Young's modulus [1,4,5]. Also suppressing the formation of the wurtzite AlN phase in the TiAl-V-N system by applying high bias voltages has been mentioned to significantly improve the mechanical properties [6].…”

“…Similar to the NbAlN coatings studied within the present study, TiAlN and ZrAlN revealed a reduction in wear with increasing temperature when tested against alumina counterparts [26][27][28]. Comparing the wear coefficients of these three coating materials, NbAlN generally seems to exhibit a better wear resistance than ZrAlN, but slightly inferior to TiAlN.…”

Nb 1-x Al x N hard coatings were synthesised by cathodic arc-evaporation with different Al contents to study its influence on the tribological properties. Ball-ondisc tests at temperatures up to 700°C were performed and the recorded coefficient of friction was generally in the range from 0.8 to 1.0. Subsequent analysis of the coating wear track and the counterpart wear scar by optical profilometry and Raman spectroscopy revealed details on the wear behaviour of the tested coatings. The best wear performance for the Nb-rich coatings was in the temperature range of 300-500°C, whereas at the maximum testing temperature the higher oxidation resistance with increasing Al content was beneficial in terms of wear resistance.
