This type of corrosion is characterized by a wormhole-like 1D morphology that can serve as a mass-flow pathway.
The discovery of this type of corrosion is significant for the understanding of material degradation mechanisms in molten salt environments, particularly in relation to next-generation nuclear power Plants that use molten salts as coolants.
The 1D wormhole corrosion is a highly localized form of penetrating corrosion that occurs in a nickel-chromium Alloy when exposed to molten fluoride salt.
