“…When the number of Cu rods was 4, 8, 16, and 32, the corresponding Cu content was 1.09 at%, 2.21 at%, 4.1 at%, and 11.08 at%, respectively. When the number of Cu rods increased from 16 to 32, the content of Cu in the film approximately doubled, induced by the presence of a single crystal Cu phase in the film [23,29], which was confirmed by subsequent XRD results. Figure 4a shows the XRD of the prepared film.…”

“…However, with an increase in Cu content, the absolute value of the system formation energy decreases, indicating that the increase in Cu content decreases the structure stability of TiN. It was found in the experiment that when the Cu content exceeded 11.08 at%, there was a single crystal phase of Cu in the coating [23]. It is simply the instability of the doping system that caused the precipitation of Cu.…”

“…Recently, Cu doped Ag clusters, Diamond-like Carbon (DLC), TiN, and other ceramic materials have been reported [11][12][13]. Researchers have carried out experimental studies on the hardness [14][15][16], corrosion resistance [17], tribological properties [18,19], and biocompatibility [20][21][22][23] of Cu doped TiN films. However, the micro-mechanism involved in the effect of Cu-doping of the crystal structure and mechanical properties of TiN has not been studied comprehensively.…”

In this study, TiN films doped with different copper contents (TiCuN) were prepared by using direct current magnetron sputtering method. The effects of Cu doping on composition, structure, and mechanical properties of TiN films were studied by energy-dispersive spectroscopy (EDS), X-ray diffraction (XRD), a Vickers microhardnessmeter, and density functional theory (DFT). The results of experimental and DFT study showed that Cu mainly replaced Ti atoms in TiN to form replacement solid solution doping. When Cu replaced Ti in TiN, a weak Cu-N (bond population varied from 0.06 to 0.11) covalent bond formed; meanwhile, the bonding strength of Ti-N (bond population varied from 0.29 to 0.4) bond adjacent to Cu increased. When Cu content was low, a small number of weak Cu-N bonds were formed, with strengthened Ti-N bond near Cu atom, resulting in an increased hardness of Cu doped TiN films. According to the theory of weak bonds, when the Cu content was increased further, the number of weak Cu-N bonds increased and TiCuN hardness decreased. With an increase in Cu content, it was found the toughness of TiCuN also increased. The results of this study will provide a theoretical and experimental guidance for improving the toughness and deformation resistance of TiN, which has a potential application in the surface modification of medical devices.

“…Additionally, it has been demonstrated that metallic nanoparticles can introduce specific functionalities to coatings, such as a low-friction coefficient, hydrophobicity, antibacterial properties, and the surface plasmon resonance effect [4,[36][37][38] (Table 1). Domingues et al [4] deposited Ag-AlN thin films via DC magnetron sputtering, and the results showed a localized surface plasmon resonance at wavelengths around 380 nm when the films were annealed at 300 • C. According to the authors, the presence of Ag particles led to a nearly flat absorption band from visible to infrared wavelengths.…”

The functional properties of the transition-metal nitride coatings can be modified by adding noble metals such as silver. The incorporation of these elements has been demonstrated to be a good strategy for improving the electrical, optical, and mechanical responses of transition-metal nitride coatings. In this investigation, we report the production of Ag-ZrSiN coatings with varying silver atomic contents, deposited using pulsed-DC reactive magnetron sputtering. The effect of the incorporation of silver on the microstructure, the morphology, and the optical and electrical properties was investigated. The results revealed a nanocomposite structure of Ag-ZrSiN with nc-Ag/nc-ZrN embedded in an amorphous SiNx phase. The electrical resistivity decreased upon the incorporation of Ag from 77.99 Ω·cm to 0.71 Ω·cm for 0.0 and 12.0 at.% of Ag, respectively. A similar decreasing trend was observed in the transmittance spectra of the coatings as the silver content increased. For the Ag-ZrSiN coating, the transmittance values decreased within the wavelength range of 2500–630 nm and then remained constant down to 300 nm, at about 13.7%. Upon further increase of the silver concentration up to 12 at.%, the transmittance values continued to decrease between 2500 and 630 nm, reaching approximately zero at 630 nm, indicating that the coating becomes opaque within that spectral range.

“…Therefore, during recent twenty years, a wide variety of solid lubricating films were produced and design by combining the intrinsic properties of some binary and ternary films which are very hard and resistant to oxidation, with specific elements which diffused up to the surface and formed a low friction tribolayer. Addition of soft metals such as Ag [16][17][18][19][20] and Cu [21][22][23][24][25], was observed to be one of the more efficient solutions to obtain self-lubrication properties at a wide temperature range. Nevertheless, the strong out-diffusion of the lubricious element and its quick depletion from the entire volume of the film only allows low friction behavior for short periods of time, leading after few minutes to the failure of the film [26][27][28][29][30].…”
