| Abstract Scope |
The requirements for more efficient and cleaner energy generation exposed structural alloys for power gener-
ation, which experience severe degradation due to hostile operating environments. Hence, high-performance
materials are needed to resist corrosion and erosion processes. The next generation of nuclear reactor systems
is expected to operate at high temperatures to achieve high thermal-to-electrical conversion efficiency and
enable cost competitiveness with conventional electrical power generation methods. MSR cooling systems
present several technical and engineering challenges due to their highly corrosive characteristics to typi-
cal materials. Amorphous metals are more corrosion-resistant than conventional metals due to the lack of
long-range periodicity, related grain boundaries, and crystal defects such as dislocations.
This presentation compares the corrosion resistance of uncoated Haynes 230 and SS316H substrates to the
same substrates coated with Fe- and Ni-based amorphous alloys. The findings indicate that the amorphous
alloys coatings provided superior corrosion resistance at 700 °C in FLiNaK. |
