“…The preferred orientation is a common phenomenon of physical vapour-deposited coatings. The deposition parameters affect the growth process, and then affect its crystal orientation [45–47]. When the bias voltage is raised, the value of TC (200) decreases, while the value of TC (220) increases.…”

AlCrNbSiTi)N coatings were prepared by arc ion plating at a bias voltage in the range of −50 to −200 V. The as-deposited coatings were all found to have a face-centred cubic structure and exhibit columnar crystal. Si 3 N 4 is distributed in the columnar grains in the form of a network, which separates the columnar grains into fine grains. Si 3 N 4 presents a crystalline state and grows coherently with the surrounding grains to form a nc-(AlCrNbTi)N/nc-Si 3 N 4 nanocomposite structure. The coating with the finest mechanical characteristics was applied at −200 V. The hardness, elastic modulus and wear rate are 34.76, 425 GPa and 0.82 × 10 −9 mm 3 N −1 m −1 , respectively. Based on the outstanding mechanical performance of the coating, it is concluded that the (AlCrNbSiTi)N protective coating has a broad range of potential applications.

“…The probable reason for the distinct oxidation behavior of the Cr coatings with and without orientations might be the oriented growth of the Cr 2 O 3 scales. [36] Considering the growth process and protective mechanism of the Cr 2 O 3 scale on the surface of Cr coating during high-temperature steam oxidation are very complex, more comprehensive analysis and research are needed in the future.…”

Cr coatings were deposited on the Zircaloy-4 alloy by multi-arc ion plating under different bias voltages from −50 to −110 V, and the microstructure, mechanical properties, and high-temperature steam oxidation behavior of these coatings were systematically investigated. The results indicate that the bias voltage significantly affects the crystal orientation, surface morphology, deposition rate, nanohardness, and bonding strength of Cr coating on the Zircaloy-4 alloy. The high-temperature oxidation behavior of the Cr coating is closely related to its crystallographic orientation. Compared with the Cr coating with relatively random grain orientations, the Cr coating with (211) preferred orientation has a dense and uniform oxide scale and has the best oxidation resistance in the steam environment at 1200°C.

“…Some dripping particles were detected on the Cr coating surface prepared by AIP, and most of the particles were smaller than 5 μm, which was related to the AIP deposition process. [21,22] Figure 2b shows the surface roughness of the Cr coating. The average value of surface roughness was approximately 0.458 μm.…”

The Cr-coated Zircaloy-4 samples were prepared by arc ion plating to enhance the high-temperature oxidation resistance of Zircaloy-4 alloys for accident tolerant fuel claddings. The oxidation tests of the Cr coating were performed under 1473 K steam for 60, 120, and 240 min. The steam oxidation tests indicated that the Cr-coated Zircaloy-4 substrate had excellent hightemperature steam oxidation resistance to protect the fuel cladding from damage for at least 240 min. The weight gains and the thickness of the oxidation scale of the samples were measured to evaluate the oxidation kinetics of the Cr coating in 1473 K steam. In addition, the diffusion and interfacial evolution were analyzed during the oxidation process, and the steam oxidation behaviors of the Cr coatings were also discussed in detail.
