摘要：
A kind of novel Gd particles-doped Fe-based amorphous metallic coating (Gd-AMC) was designed and produced by thermal spraying technique. The thermal neutron absorption cross-section for the coating containing 4.8 wt% Gd is 14.7 times higher than that of borated stainless steel (BSS) substrate. It is also worth noting that the localized corrosion resistance for Gd-AMCs is considerably superior to that for BSS substrate, which is closely attributed to the rapidly formed protective passive film on amorphous matrix through novel "dissolutionpassivation" processes. This work provided a new strategy for the design of corrosion-resistant neutron absorbing materials.
