Corrosion-Resistant Coating Based on High-Entropy Alloys

Metal corrosion leads to serious resource waste and economic losses, in severe cases, it can result catastrophic safety incidents. As a result, proper coatings are often employed separate metal alloys from the ambient environment thus prevent or at least slow down corrosion. Among various materials, high-entropy alloy (HEA coating) have recently received lot of attention due their unique entropy-stabilized structure, superior physical chemical properties, excellent resistance. To address recent developments remaining issues HEA coatings, this paper reviews primary fabrication methods elemental compositions highlights effects on resistance properties. It is found that FeCoCrNi-based refractory prepared by laser/plasma cladding method typically show better also briefly discusses future directions toward high-performing corrosion-resistant based design.
