1D Wormhole Corrosion : New Form Of Corrosion

News: A novel type of corrosion called as 1D wormhole corrosion has just been identified by scientists.

• The 1D morphology of this form of corrosion is characterised by wormhole-like features that can behave as mass-flow pathways.
• In particular, it has implications for next-generation nuclear power plants that use molten salts as coolants. The discovery of this type of corrosion is significant for the understanding of material degradation mechanisms in molten salt environments.
• When exposed to molten fluoride salt, a nickel-chromium alloy develops the highly localised form of penetrating corrosion known as 1D wormhole corrosion.
• Along grain boundaries, a percolating network of tunnels forms as a result of this kind of corrosion.
• These molten salt-filled tunnels leave gaps along the grain boundaries.
• These molten salt-filled tunnels leave gaps along the grain boundaries.
• One feature of the 1D wormhole corrosion is its wormhole-like 1D morphology, which can behave as a mass-flow channel.
• The finding of 1D wormhole corrosion has significant ramifications for our comprehension of the mechanics underlying material deterioration in molten salt settings.
• Molten salts are a top contender for coolants in nuclear power facilities of the next generation.
• These power plants are being developed to be safer, more effective, and more environmentally friendly than nuclear power plants now in use.
• Because molten salts have a high boiling point and excellent heat conductivity, using them as coolants is particularly appealing.
• They are therefore perfect for generating electricity and transporting heat away from the reactor core.
