Corrosion and Wear-Resistant Coatings for Nuclear Applications by using High-Pressure Cold Spray Technology
The Cold Spray process is well known for high powder feedstock deposition efficiency and low-temperature processes leading to oxygen-free deposits. The CS process offers substantial applications, for example, in-situ structural or dimensional restoration and surface coatings to enhance corrosion, fatigue, and wear resistance.
It is of immense importance in the nuclear power industry to use long-lasting storage and transport containers for nuclear waste or materials. Therefore, corrosion resistance is of great importance. Some potential applications of CS technology include mitigation and repair of stress corrosion cracking, intergranular attack, flow accelerated corrosion, and other types of corrosion by applying a protective coating to isolate the component's structural material from the corrosive environments. On the other hand, the technology can also be used for nuclear energy applications, including coatings for enhancements in wear resistance and heat transfer near-net-shape manufacturing.
