“…As shown in Figure g, no intermixing or defects appear, which further confirms the epitaxial growth of γ′-Fe 4 N by the fast Fourier transform and XRD pole figure. Therefore, the γ′-Fe 4 N film can be epitaxially grown on flexible mica even though a large lattice mismatch exists, which should be attributed to the misfit dislocation. , Misfit dislocation is the distortion of the lattice of the γ′-Fe 4 N films near the interface, which can release the large strain induced by the lattice of the substrate. Normally, the misfit dislocation appears in the heterogeneous systems with a large lattice mismatch between the film and the substrate, such as a −9.92% lattice mismatch of γ′-Fe 4 N/MgO .…”

The strain modulation on the magnetic and electronic transport properties of the ferromagnetic films is one of the hot topics due to the practical applications in flexible and wearable spintronic devices. However, the large strain-induced saturation magnetization and resistance change is not easy to achieve because most of the ferromagnetic films deposited on flexible substrates are polycrystalline or amorphous. Here, the flexible epitaxial γ′-Fe 4 N/mica films are fabricated by facing-target reactive sputtering. At a tensile strain with a radius of curvature (ROC) of 3 mm, the saturation magnetization (M s ) of the γ′-Fe 4 N/mica film is tailored significantly with a maximal variation of 210%. Meanwhile, the magnetic anisotropy was broadly tunable at different strains, where the out-of-plane M r /M s at a tensile strain of ROC = 2 mm is six times larger than that at the unbent state. Besides, the strain-tailored longitudinal resistance R xx and anomalous Hall resistivity ρ xy appear where the drop of R xx (ρ xy ) reaches 5% (22%) at a tensile strain of ROC = 3 mm. The shift of the nitrogen position in the γ′-Fe 4 N unit cell at different bending strains plays a key role in the strain-tailored magnetic and electronic transport properties. The flexible epitaxial γ′-Fe 4 N films have the potential applications in magneto-and electromechanical wearable spintronic devices.

“…Part of the amorphous zone was detected in the TiSiN film, which may be related to the existence of SiN x [ 15 , 26 ]. The indexed selected−area electron diffraction (SAED) image in Figure 5 e presents polycrystalline diffraction rings with randomly distributed spots, indicating that this coating is composed of fcc single−phase solid solution [ 27 ]. This finding is similar to the XRD pattern.…”

Impact Abrasive Wear Property of CrAlN/TiSiN Multilayer Coating at Elevated Temperatures

The impact wear property of hard coatings at elevated temperatures is of particular interest for applications in nuclear power plants. This study evaluated the impact wear behavior of two CrAlN/TiSiN coatings with and without sand. Alternately grown CrAlN and TiSiN films with modulation periods of 455 and 19 nm were formed in a columnar structure. The nanomultilayer shows better impact wear resistance than multilayer films with and without sand. The energy absorption rate has a similar trend to wear rate, leading to lower rebound velocity and peak impact force of the nanomultilayer compared with that of the multilayer. CrAlN/TiSiN coatings can protect the 308L substrate from oxidation. The dominant impact wear mechanism without sand is plastic deformation, and this wear region can be defined as the percussive zone. Peeling occurs on the multilayer surface without sand after 104 percussions, leading to rapid oxidation of the 308L substrate at 500 °C. Due to the abrasion effect, the wear rate of the sample with sand increases by an order of magnitude compared to the sample without sand. The wear scar of the sample with sand can be divided into the mixing zone and the sand−affected zone from inside to outside. Fe oxides are formed beyond the unbroken coating, which may be related to the outward diffusion of Fe.

“…The result could be ascribed to the multilayer structure in nano scale with relatively small periodic thickness of 15 nm of the HEAN-N165 coatings. The multilayer structure revealed more grain boundaries to hamper slip of dislocations [45]. In addition, the HEAN-N165 possessed the best ability to resist the plastic deformation where H 3 /E* 2 was 0.2 GPa.…”

Multi-element material coating systems have received much attention for improving the mechanical performance in industry. However, they are still focused on ternary systems and seldom beyond quaternary ones. High entropy alloy (HEA) bulk material and thin films are systems that are each comprised of at least five principal metal elements in equally matched proportions, and some of them are found possessing much higher strength than traditional alloys. In this study, CrVTiNbZr high entropy alloy and nitrogen contained CrVTiNbZr(N) nitride coatings were synthesized using high ionization cathodic-arc deposition. A chromium-vanadium alloy target, a titanium-niobium alloy target and a pure zirconium target were used for the deposition. By controlling the nitrogen content and cathode current, the CrNbTiVZr(N) coating with gradient or multilayered composition control possessed different microstructures and mechanical properties. The effect of the nitrogen content on the chemical composition, microstructure and mechanical properties of the CrVTiNbZr(N) coatings was investigated. Compact columnar microstructure was obtained for the synthesized CrVTiNbZr(N) coatings. The CrVTiNbZrN coating (HEAN-N165), which was deposited with nitrogen flow rate of 165 standard cubic centimeters per minute (sccm), exhibited slightly blurred columnar and multilayered structures containing CrVN, TiNbN and ZrN. The design of multilayered CrVTiNbZrN coatings showed good adhesion strength. Improvement of adhesion strength was obtained with composition-gradient interlayers. The CrVTiNbZrN coating with nitrogen content higher than 50 at.% possessed the highest hardness (25.2 GPa) and the resistance to plastic deformation H3/E*2 (0.2 GPa) value, and therefore the lowest wear rate was obtained because of high abrasion wear resistance.
