Corrosion- and Wear-Resistant Coatings for Nuclear Applications by using High-Pressure Cold Spray Technology
The Cold Spray process is renowned for its high deposition efficiency of powder feedstock and its ability to operate at low temperatures, resulting in the formation of oxygen-free deposits.
Cold Spray technology offers a wide range of applications. For instance, it can be employed for in-situ structural or dimensional restoration and for applying surface coatings that enhance resistance to corrosion, fatigue, and wear.
Within the nuclear power industry, the use of durable storage and transport containers for nuclear waste or materials is of paramount importance. As a result, corrosion resistance holds significant value. Cold Spray technology has various potential applications, including the mitigation and repair of stress corrosion cracking, intergranular attack, flow accelerated corrosion, and other types of corrosion. This is achieved by applying protective coatings to isolate the structural material of the component from corrosive environments.
Conversely, the technology can also find utility in nuclear energy applications. This includes the application of coatings to improve wear resistance and heat transfer, as well as the facilitation of near-net-shape manufacturing processes.
