“…The initial surface morphology of the CrAl coatings is shown in Figure 4a-d. Similar to the case for the surface of other coatings deposited by multi-arc ion plating [22][23][24][25][26][27], droplet-like particles appeared on the surface of our four coatings. The surface of sample A was flatter and more homogeneous, whereas a greater number of larger droplets appeared on the surface of samples B, C, and D. This is mainly because the melting point of Al is lower than that of Cr, and therefore, it is easy to form large droplets during the deposition process.…”

The oxidation behaviors of Cr, Cr93.4Al6.6, Cr58.1Al41.9, and Cr34.5Al65.5 coatings, deposited by using multi-arc ion plating technology, at high temperature were studied. The weight gain, oxide thickness, morphology, and phase composition of the coatings before and after oxidation were analyzed in detail. The results show that there is an Al content window available for tuning the oxidation behaviors of the CrAl-based coatings. The Cr93.4Al6.6 coating is considered to be most protective and can effectively improve the high-temperature oxidation resistance of the substrate; whereas, too high an Al content has a harmful effect on the antioxidant properties of the coatings. The oxidation mechanism of Cr and CrAl coatings were also discussed.

“…For the Cr-N x coatings, the hardness of both the ceramic-like CrN and Cr 2 N coatings were considerably higher than that of the metal-like Cr coating, indicating that an increase in the N content can improve the hardness of the Cr-N x coatings. The addition of N makes the lattice structure of the CrN coating appear as a face-centered cubic structure, substantially improving the hardness of the coating [24]. Unlike the Cr coating and Zr-4 alloy, the hardness of both the CrN and Cr 2 N coatings were higher than that of the friction pair.…”

“…The flow of coolant around the fuel rods in the reactor primary circuit can cause the rods to vibrate, known as flow-induced vibration (FIV), which leads to the relative slip displacement between the fuel rod and the grid spring that causes the degradation of the fuel rod, known as grid-to-rod fretting (GTRF) [19][20][21][22]. Under conditions of high neutron irradiation and thermal relaxation, the grid-to-rod gap gradually increases, resulting in the increased vibration of the fuel rod under the primary coolant [23,24]. Notably, GTRF is the most common cause of failure in fuel cladding materials [25].…”

“…In studies on the friction and wear properties of Cr-based ATF coatings, Lee et al found that a CrAl coating with a high-load support capability considerably improved the wear performance of the Zr-4 alloy by forming a load-bearing layer [26]. Our research group has thoroughly studied the influence mechanisms of Si [24] and Al [27] on the friction and wear properties of Cr-based ATF coatings, including the effect of N on the oxidation properties of Cr-based ATF coatings [16]. However, the effect of N on the friction and wear properties of Cr-based ATF coatings has not been studied in depth.…”

Friction and wear resistance are important factors that affect the selection of accident-tolerant fuel coating materials. In this study, the wear behavior of a series of Cr-Nx coatings with different N contents was investigated using a reciprocating sliding tester. The coating morphology, change in the coefficient of friction during the friction and wear tests, and wear volume after the friction and wear tests, were characterized and discussed in detail. The results show that the Cr2N coating has better anti-friction and wear resistance behaviors than the Cr and CrN coatings under anhydrous and aqueous conditions. In addition, the water environment promoted the wear of the Zr-4 alloy and Cr coatings and inhibited the wear of the CrN and Cr2N coatings. The mechanisms of friction and wear were also discussed.

Functional coatings, including organic and inorganic coatings, play a vital role in various industries by providing a protective layer and introducing unique functionalities. However, its design often involves time‐consuming experimentation with multiple materials and processing parameters. To overcome these limitations, data‐driven approaches are gaining traction in materials science. In this paper, recent advances in data‐driven materials research and development (R&D) for functional coatings, highlighting the importance, data sources, working processes, and applications of this paradigm are summarized. It is begun by discussing the challenges of traditional methods, then introduce typical data‐driven processes. It is demonstrated how data‐driven approaches enable the identification of correlations between input parameters and coating performance, thus allowing for efficient prediction and design. Furthermore, carefully selected case studies are presented across diverse industries that exemplify the effectiveness of data‐driven methods in accelerating the discovery of new functional coatings with tailored properties. Finally, the emerging research directions, involving integrating advanced techniques and data from different sources, are addressed. Overall, this review provides an overview of data‐driven materials R&D for functional coatings, shedding light on its potential and future developments.
