“…These results were consistent with the study of NbN-Ag composite films by Ju et al [9]. From Figure 5e, two sets of lattice fringes with lattice spacing of about 0.236 nm and 0.259 nm were observed, which interrelated with hcp-NbN (101) and fcc-NbN (111).…”

“…The inset in Figure 5a TEM and HRTEM of NbCN-12.9 at.% Ag films are shown in Figure 5d-f. As drawn in Figure 5d, a columnar crystal texture was found for the NbCN-Ag film, also showing that the added Ag particles were well dispersed in the film. These results were consistent with the study of NbN-Ag composite films by Ju et al [9]. From Figure 5e, two sets of lattice fringes with lattice spacing of about 0.236 nm and 0.259 nm were observed, which interrelated with hcp-NbN (101) and fcc-NbN (111).…”

“…Recently, soft metals (such as silver, aluminum, and copper) were added into TMN based films to reduce the friction coefficient over a wide temperature range [7][8][9]. As expected, a novel self-lubricated CrN-Ag nanocomposite film was elucidated by Mulligan et al [10], indicating that the addition of…”

Abstract:In this study, reactive magnetron sputtering was applied for preparing NbCN-Ag films with different Ag additions. Ag contents in the as-deposited NbCN-Ag films were achieved by adjusting Ag target power. The composition, microstructure, mechanical properties, and tribological properties were characterized using energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), high resolution transmission electron microscopy (HRTEM), Raman spectrometry, nano-indentation, and high-temperature sliding wear tests. Results indicated that face-centered cubic (fcc) NbN, hexagonal close-packed (hcp) NbN and fcc Ag, amorphous C and amorphous CN x phase co-existed in the as-deposited NbCN-Ag films. After doping with 2.0 at.% Ag, the hardness and elastic modulus reached a maximum value of 33 GPa and 340 GPa, respectively. Tribological properties were enhanced by adding Ag in NbCN-Ag films at room temperature. When the test temperature rose from 300 to 500 • C, the addition of Ag was found beneficial for the friction properties, showing a lowest friction coefficient of~0.35 for NbCN-12.9 at.% Ag films at 500 • C. This was mainly attributed to the existence of AgO x , NbO x , and AgNbO x lubrication phases that acted as solid lubricants to modify the wear mechanism.

“…As the increase of the Ti and B contents in the films, as shown in Figure 2b, the columnar-growth and dense structure disappears and the Cr 33. 4 Figure 2 illustrates the cross-sectional SEM images of Cr-Ti-B-N films with various Ti and B contents. As illustrated in the Figure 2a, the binary CrN film exhibits a columnar-growth and dense structure.…”

“…were effective to decrease the friction coefficient over broad working temperature range. Lihua Yu et al [3] synthesized the WCN-Ag film containing 6.6 at.% Ag has a low friction coefficient (<0.4) in the temperature range of 25-600 • C. The NbN-Ag composite films [4] reported a decreased friction coefficient from 0.65 at 0 at.% Ag to 0.35…”

Abstract:In this study, the Cr-Ti-B-N composite thin films with different Ti and B contents in the films were fabricated by a reactive magnetron sputtering system using chromium (Cr) and TiB 2 targets. The microstructure, mechanical properties, and friction properties over broad ranges of temperature were detected by XRD, SEM, TEM, nano-indentation, 3D profilometer, and tribometer. It was found that the Cr-Ti-B-N films exhibited a double face-centered cubic (fcc)-CrN and amorphous-BN structure. As the Ti and B elements were introduced, the hardness and elastic modulus of Cr-Ti-B-N films increased from 21 and 246.5 GPa to a maximum value of approximately 28 and 283.6 GPa for Cr 38.7 Ti 3.7 B 6.4 N 51.2 film, and then decreased slightly with a further increase of Ti and B contents. The hardness enhancement was attributed to the residual compressive stress. The friction and wear resistance of the film was improved obviously by the addition of Cr and B, as compared with the CrN film under 200 • C.
