“…For the sample C1 (Figure 4 C1), the binding energy at 396.2 eV was due to CrN and higher binding energy at 397.4 eV was identified with Cr 2 N bond nitrogen (agreeing with the published binding energy values [20,21]) with clear predominance of CrN phase in the film. These results mean that CrN and Cr 2 N coexist in the sample C1 as the composition calculation result and XRD result.…”

CrN and CrN /a-C:H nanocomposite films were deposited on Si substrates by the magnetron sputtering technique. The structure, chemical state, and friction behavior of the CrN /a-C:H films prepared at various CH 4 content were studied systematically. The CrN film shows strong (111) and (220) orientation, while the CrN /a-C:H films consist of the nanocrystalline CrN or Cr particles embedded in an amorphous hydrocarbon (a-C:H) matrix and show weak diffraction peaks, which is in accordance with the XPS analysis results. The typical Raman D and G peaks are observed, indicating that the separated amorphous carbon or CN phase appears in the CrN /a-C:H films. However, no chromium carbide was observed in all the as-deposited samples. From the SEM graphs, all the deposited films depicted a dense and compact microstructure with well-attached interface with the substrate. The average friction coefficient of the CrN /a-C:H films largely decreased with increasing CH 4 content.

“…Thus, the grain boundary hardening by Hall-Petch relationship would take place. Furthermore, the codeposition of amorphous Si 3 N 4 phase among (Cr, Si)N crystallites would enhance cohesive energy of the interphase boundaries [7]. On the other hand, the hardness reduction with further increase of Si content after maximum hardness in Fig.…”

“…Especially, the wear curve of CrSi(9.3 at.%)-N coated tool slightly increased. Also, this is why the tribo-layers of SiO 2 and Si(OH) 2 were easily formed with increase of Si content [7,10]. In the case of Cr-Si(9.3 at.%)-N coated tool, the semi-dry (MQL) cutting showed superior wear resistance which led by its lower cutting force compare to dry cutting.…”

“…As to Cr-N coatings, many efforts have been devoted to CrN x coatings deposited with fixed N 2 flux ratio values [9][10][11][12][13][14]. Zhou et al [15] found that, compared to homogeneous CrN coatings, gradient CrN x coatings exhibit improved corrosion resistance due to its composition and the discontinuous crystallite boundaries, which decrease the opportunity of pore formation. As far as our best knowledge, there are few reports concentrating on mechanical properties of compositionally gradient CrN x coatings.…”
