Scientists have recently discovered a new form of corrosion known as the 1D wormhole corrosion.
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.
This type of corrosion leads to the development of a percolating network of tunnels along grain boundaries.
These tunnels are filled with molten salt and leave voids along the grain boundaries.
