High temperature steam-oxidation behavior of arc ion plated Cr coatings for accident tolerant fuel claddings

High-temperature oxidation resistance of chromium-based coatings deposited by DLI-MOCVD for enhanced protection of the inner surface of long tubes

“…A single layer of metallic chromium is one of the most investigated solutions. They are deposited by thermal spray [9][10][11], laser cladding [12] or PVD (Physical Vapor Deposition) [13][14][15][16]. Other coating materials and architectures are developed like non-metallic coatings, pure metals, intermetallics, metallic alloys coatings, oxides, carbides including ternary carbides as MAX phases [17,18], nitrides, composites and multilayers [19].…”

Application and Development Progress of Cr-Based Surface Coatings in Nuclear Fuel Element: I. Selection, Preparation, and Characteristics of Coating Materials

“…In terms of accident resistance, Cr coatings have been found to demonstrate outstanding resistance to high-temperature steam oxidation. The oxidation rate of a coated Zr alloy cladding is lower by at least one order of magnitude compared to an uncoated cladding [21,22,73,104,108,109]. Furthermore, Cr coatings greatly reduce the hydrogen absorption of claddings, alleviating the risk of hydrogen-induced embrittlement.…”

“…Since the inception of the ATF concept and its development, many countries have accumulated extensive experience and achievements in the research and development of zirconium alloys with Cr-based coatings [14][15][16][17][18][19][20][21][22][23][24][25]. However, existing literature and reports have not been able to establish a systematic framework.…”

Materials selection for nuclear applications: Challenges and opportunities

“…Four systems have been studied: 1) silicon-carbide (SiC)-based composites [16][17][18], 2) iron-chromium-aluminum (Fe-Cr-Al) alloys [19,[21][22][23], 3) coated zirconium [24], and 4) molybdenum (Mo) [25]. These four systems were chosen as balanced compromise among the application's requirements.…”
