“…Nitride coatings, MAX phase coatings, carbide coatings, pure metal coatings and high-entropy alloy coatings are the main coatings [4][5][6][7][8][9][10]. To the best of our knowledge, the metallic Cr coating is considered to be the best choice for pressurized water reactor (PWR) due to their optimal corrosion resistance in high-temperature steam [4,[10][11][12][13][14][15][16].…”

A 700 V pulsed laser was used for the surface treatment of Zircaloy-4. Phases including the treatment layer, morphology and the distributions of alloying elements of the treatment layer were detected via X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM). The results showed that the laser surface treatment (LST) layer is also α-Zr phase layer, the morphology of the treatment layer was “cauliflower-like” and the Fe-Cr precipitates in the LST layer were dissolved. The corrosion tests of the LST and the no-laser surface treatment (NLST) specimens were conducted in steam at 1100 °C using TGA (NETZSCH STA 449 F). The results showed that LST can enhance the corrosion resistance of the Zircaloy-4 in high-temperature steam. More microcracks distributed in the oxide film formed on the NLST specimen than on the LST specimen. And the volume fraction of the tetragonal zirconia (t-ZrO2) phase in the oxide film on the surface of the LST specimen was higher than that of NLST specimen. The main reason for this phenomena could be attributed to the dissolving Fe-Cr precipitates and higher solid solution of Fe and Cr in the laser treatment layer.

Protective nitride coatings are widely used in various industrial fields due to their exceptional mechanical, structural, and chemical stabilities under various harsh environments. Many nitride coatings have the inherent barrier function against the attack of environmental agents, making them splendid materials for, e.g., hydrogen permeation barriers, high-temperature-environment barriers, and tribocorrosion coatings. However, the long-term contact with aggressive environments may still result in the degradation of these coatings, where many processes occuring on various atomistic microstructures (e.g., surfaces, vacancies, grain boundaries, and coating/substrate interfaces) usually play the key roles. Here, we make a timely review on the microscopic mechanisms associated with the interactions between various microstructural entities and environmental agents, for which the first-principles calculations will be powerful in quantitatively revealing the essential interatomic bondings and thermodynamic/kinetic trends therein. Many successful application cases and possible future directions of first-principles calculations for these three kinds of nitride coatings are discussed here, which can shed much light on more optimization ways towards superior and durable nitride coatings through precise chemical tuning and structural design in the future.
