“…As shown in Figure 3a, all the Ti2p spectra can be fit to three spin-orbital doublet peaks (Ti2p 3/2 and Ti2p 1/2 ) separated by 6.0 eV. The Ti2p 3/2 peaks, located at about 456.2 ± 0.2 eV, 457.7 ± 0.2 eV, and 455.7 ± 0.2 eV, correspond to Ti-O-N bonds [13,29,30], Ti-O (TiO 2 ) bonds [13,31], and Ti-Al-Cr-N (CrAlTiN solution solid) bonds [6,30], respectively. The presence of oxides and oxynitrides in the coatings can be attributed to the vacuum chamber and exposure to air [32], as titanium has a higher affinity for O atoms.…”

CrAlTiN-Si coatings have demonstrated their ability to prolong the operational life and improve the performance of cutting tools, primarily attributable to their exceptional mechanical, thermal, and tribological properties. Consequently, this investigation focused on the deposition of CrAlTiN-Si coatings utilizing the high-power impulse magnetron sputtering (HiPIMS) technique. The chemical composition, morphology, and microstructure of these coatings, as well as their mechanical and tribological properties, were investigated. The obtained results revealed that the incorporation of silicon into the CrAlTiN matrix significantly influenced the chemical composition, microstructure, and mechanical properties of the coatings. Specifically, silicon contents ranging from 0 to 1.0 at.% led to the formation of a face-centered cubic (fcc) solid solution within the coatings, resulting in a reduction in the lattice parameter from 0.412 nm to 0.409 nm. However, when the silicon content reached 1.9 at.%, a nanocomposite phase comprising an fcc solid solution of CrAlTiSiN and an amorphous phase of SiNx was observed, along with an increase in the lattice parameter from 0.409 nm to 0.413 nm. An XPS analysis confirmed the presence of oxides in all the coatings, but only the sample with a silicon content of 1.9 at.% showed the presence of Si-N bonds. Furthermore, all the coatings exhibited a distinctive cauliflower-type morphology. The nano-hardness testing demonstrated that the incorporation of silicon resulted in coatings with high nano-hardness values, from 20.0 GPa for the sample without silicon to 22.2 GPa when the silicon content was 1.9 at.%. Moreover, as the Si content increased, the presence of silicon contributed to enhancements in the toughness and fracture resistance of the coating.

“…Scholars have attempted to add Al to TiN coatings to form a TiAlN coating system with improved thermal stability, high-temperature oxidation resistance, and heat fatigue resistance [8]. TiAlCN coatings are a new type of quaternary coating developed on the basis of ternary TiAlN coatings, and they have better plasticity, toughness, and friction and wear resistance than those of TiAlN coatings [9]. Wang et al [10] prepared Al2O3-Ag-Cu-Ti composite coatings on GCr15 bearing steel using plasma spraying technology.…”

In order to enhance the surface properties of GCr15 bearing steel, a TiAlCN coating with a low friction coefficient, high hardness, and excellent adhesion was fabricated. The TiAlCN multilayer coating was deposited onto the GCr15 bearing steel surface using magnetron sputtering technology, and optimal coating parameters were achieved by adjusting the number of layers, sputtering power of the graphite target, and coating duration. The experimental results showed that adding Cr/CrN as a transition layer between GCr15 bearing steel and TiAlCN significantly improved multiple properties of the coating. Adding carbon atoms caused TiAlN to dissolve into a TiAlCN structure, enhancing multiple properties of the coating. With the increase in the sputtering power of the graphite target material, the hardness, friction, and wear performance of the coating showed a trend of first increasing and then decreasing. The hardness of the coating gradually increased with time, and the friction coefficient and wear amount first decreased and then increased. When the sputtering power of the graphite target material was 100 W and the coating time was 4800 s, the coating performance was optimal. The hardness was 876 HV, the friction coefficient was 0.42, the wear amount was 1 × 10−4 g, and the wear rate was 2.8 × 10−6 g/m·N under optimal process parameter conditions.
