“…In high-entropy ceramic films, the metal elements share cation positions and the nonmetallic elements occupy anionic positions, which forms a new material system and has a unique microstructure [11,14]. Researchers studied the effect of deposition parameters on film properties [15][16][17][18][19][20]. With the increase in bias potential on the substrate, the hardness of (TiZrHfVNb)N coatings increases.…”

In order to investigate the effect of Co contents on the structure and cavitation erosion property, NiTiAlCrCoxN films were prepared by the magnetron sputtering system. The X-ray diffractometer (XRD), the scanning electron microscope (SEM) and the energy dispersive spectrometer (EDS) were used to characterize the structure and morphology of the films. The nanoindenter and the scratch tester were used to analyze the mechanical properties of the films. Cavitation erosion experiments were carried out by the ultrasonic vibration cavitation machine. The results show that NiTiAlCrCoxN films with different Co contents have a simple face-centered cubic (FCC) structure and show a preferred orientation on the (200) crystal plane. The diffraction angle on the (200) crystal plane decreases and the interplanar spacing increases with the increase in Co content in NiTiAlCrCoxN films. NiTiAlCrCoxN films exhibit a typical columnar crystalline structure. With the increase in Co content, the nanohardness of the films increases and the elastic modulus of the films decreases, while the mass loss of cavitation erosion monotonously increases except for the film with a 1.2 Co molar ratio. The NiTiAlCrCo1.4N film has a minimum hardness of 13.264 GPa, a maximum elastic modulus of 253.22 GPa and a minimum mass loss of 0.72 mg in the cavitation erosion experiment. The NiTiAlCrCo1.4N film exhibits the best cavitation corrosion resistance because the addition of the Co element enhances the solid solution strengthening effect and the NiTiAlCrCox1.4N film with the biggest elastic modulus has better elasticity to reduce the micro jet impact.

“…In addition, the multimodal WC-12Co coating exhibited the best cavitation resistance than the other two coatings due to its internal dense nanostructure and strong cohesive strength. Similarly, Bao et al [33] prepared two coatings via laser cladding technology for comparison to study the effect of WC on the cavitation resistance of high-entropy alloys. The results showed that the microhardness of the WC-added coating was higher than that of the non-WC coating, and the addition of WC significantly weakened the degree of cavitation damage.…”

The WC-Co composite coating was prepared on SS 316L by plasma arc welding technology. The microstructure, phase composition, and microhardness of the WC-Co composite coating were thoroughly studied. The corrosion behaviour including electrochemical corrosion, cavitation erosion, and erosion corrosion was tested. The results showed that the WC-Co coating exhibited a good metallurgical bond with the substrate. The average microhardness of the WC-Co coating reached 1785 HV, which was 9.4 times that of the SS 316L. The corrosion current density of the WC-Co composite coating was one order of magnitude lower than that of the substrate. Meanwhile, the cumulative mass loss of cavitation erosion and erosion corrosion of the WC-Co composite coating was much lower than that of the SS 316L.

“…CoCrFeNiTiMo coatings have a higher hardness, better adhesive strength, and better cavitation erosion resistance in 3.5 wt% NaCl solution than Ti alloy [18]. Non-metallic elements such as H, N, C, and B are doped into HEA to form HEA composite films, which have better properties due to grain boundary wetting and second-phase strengthening [19][20][21][22][23]. The AlCrTiZrV coating exhibits an amorphous state, but the (AlCrTiZrV)N coating is crystallized and exhibits preferred orientation on the (200) plane.…”

In order to explore the effect of modulation period on the structure and properties of TiSiN/NiTiAlCoCrN nanomultilayer films, the films were deposited on 304 stainless steel via a magnetron sputtering system. The structure and element distribution of the films were observed via X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDS). The cavitation erosion of the films was investigated using an ultrasonic vibration cavitation machine. The results show that the TiSiN/NiTiAlCoCrN nanomultilayer film exhibits a face-centered cubic (FCC) structure and preferred orientation on the (200) crystal plane. TiSiN/NiTiAlCoCrN nanomultilayer films grow in the form of columnar crystals, which grow perpendicularly to the direction of the substrate. With increasing modulation periods, the hardness, elastic modulus, and adhesive force firstly increase and then decrease. When the modulation period is 11 nm, the TiSiN/NiTiAlCoCrN nanomultilayer film has the biggest hardness of (14.649 ± 0.591) GPa, elastic modulus of (249.065 ± 10.485) GPa, and adhesive force of 11.3 N. With increasing modulation periods, the mass loss firstly decreases and then increases. When the modulation period is 11 nm, the mass loss is the minimum of 0.6 mg. There are two reasons for improving the cavitation erosion resistance of the films. The TiSiN/NiTiAlCoCrN nanomultilayer film has the highest hardness, and the interfaces of the nanomultilayer film can hinder the generation and expansion of cavitation pits.
