About this Research Topic
The field of materials science is increasingly focused on developing advanced materials capable of withstanding extreme environments, such as those found in high-pressure steam systems, solar thermal storage, and accident-tolerant nuclear fuel assemblies. The current challenge lies in the fact that no single material can meet all of the requirements for these demanding conditions, leading to a surge in research on composite materials that offer both corrosion resistance and high-temperature durability. The concept of "defense in depth" as defined by the US Nuclear Regulatory Commission, emphasizes the need for multiple layers of protection in power plants, which has further driven the need for innovative materials.
Recent studies have explored the potential of ceramics and composites to meet these demands, but challenges remain, particularly in ensuring compatibility between coatings and substrates. The brittleness of ceramic coatings poses significant issues, such as de-bonding and corrosion at failure cracks, highlighting the need for further research into more resilient solutions, such as self-healing ceramics.
This Research Topic aims to explore the development and application of radiation-tolerant coatings for use in extreme environments, such as the nuclear fuel cycle. The primary objective is to investigate ceramics, composites, and their substrates that can effectively combine the refractory and corrosion resistance of ceramics with the ductility and formability of metals.
Key questions to be addressed include how to enhance the compatibility between coatings and substrates, how to address the brittleness of ceramic coatings, and how to develop self-healing properties in these materials. By tackling these questions, this Research Topic seeks to advance the understanding and application of these materials in extreme environments.
We welcome articles addressing, but not limited to, the following themes:
• Nuclear alloys
• Self-healing ceramics
• High-temperature ceramics
• High entropy alloy ceramics
• SiC/SIC composites
• MAX phases
• Coating methods.
