“…Among various films, nano-multilayer or nanocomposite systems have been the focused issue [1][2][3]. Due to excellent properties in hardness, adhesive strength, wear and corrosion resistance, transition-metal nitrides are commonly applied as hard and protective films on tool steel [4][5][6][7].…”

“…For HfN material (see Fig. 2, a) the peaks at 523.2, 397.6, 224.8, and 18.4 eV correspond to O1s, N1s, Hf4d 5 , and Hf4f binding energies, respectively. The change of binding energy compared to HfN verifies the formation of binary Hf-N compound.…”

“…Control of the microstructural and surface morphological evolution of polycrystalline transition metal nitride films is essential for the performance and lifetime of coated tools. Many transition metal nitrides such as titanium nitride/vanadium nitride (TiN/VN), titanium nitride/niobium nitride (TiN/NbN), and tungsten/tungsten nitride (W/WN) with excellent mechanical properties have been studied [4,5]. The growth rate of such multilayered structures with nanometer-scale dimensions has attracted much attention from the scientific and industrial community.…”

“…Ternary Cr 0.6 W 0.4 N films were found to exhibit a fine-grained dense morphology without apparent superstructure, low friction and high hardness [25]. CrN/WN superlattices have been shown to noticeably improve hardness over single layer CrN or WN films [26].…”

A few reports on ternary and quaternary coatings of WC with other elements indicate good prospects for these material systems. The present study focuses on the formation of quaternary WCeCreN and WCeAleN coatings during the simultaneous reactive RF-magnetron sputtering of tungsten carbide and Al or Cr targets in an argon/ nitrogen gas mixture. The resulting coatings, with thicknesses of 3.5 mme8.2 mm, were characterized by using several analytical techniques including X-ray diffraction, SEM/EDS, AFM, and X-ray photoelectron spectroscopy. WCeCreN and WCeAleN coatings with high levels of tungsten (i.e. more than 50 at.% of the total metal content) demonstrated dense microstructure. Coatings with lower tungsten content formed columnar grain microstructure, with different surface morphologies depending on the process parameters. It was proposed that crystalline tungsten carbide (with partial N-substitution of C atoms) and chromium (or aluminum) nitride phases coexist in the coatings when the amount of tungsten was greater than 50 at.% of the total metal content; while at lower tungsten content, the dominating crystalline phase is either W-doped CrN 1Ày or AlN 1Ày solid solution, with WC 1Àx and small amounts of free sp 2 -bonded carbon present as X-ray amorphous phases.
