Corrosion-Resistant Coating Based on High-Entropy Alloys

Metals, Год журнала: 2023, Номер 13(2), С. 205 - 205

Опубликована: Янв. 20, 2023

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.

Mechanical properties and wear behaviors of FeCoNiCrMnTix high-entropy alloys manufactured by vacuum arc melting

Journal of Materials Research and Technology, Год журнала: 2024, Номер 30, С. 1962 - 1977

Опубликована: Март 30, 2024

FeCoNiCrMnTix (x = 0, 2, 4, 6 wt%) high-entropy alloys (HEAs) were prepared using vacuum arc melting. The microstructure, mechanical and wear properties of the HEAs investigated XRD, OM, SEM, Vickers hardness, tensile tests friction tests. crystal structure consists FCC BCC, precipitation strengthening phase Ni3Ti inhibits to promote formation BCC. dendrites (DR) enriched with Fe, Co, Cr. Ni, Mn, Ti aggregated between inter-dendrites (IR) BCC phase. addition FeCoNiCrMn HEA decreased grain size. FeCoNiCrMnTi6 reaches a maximum microhardness approximately 293 HV higher than equiatomic (∼151 HV). significant increase in hardness resistance is attributed solid solution strengthening, refinement, hardening. With increasing content, yield strength increased from 296 601 MPa average coefficient (COF) gradually decreased. Tensile fracture characterized by ductile brittle fracture. generated oxide layer protects alloy matrix during friction, mechanism transforms adhesive abrasive wear.

The ability to endure extreme corrosion in challenging environments is reduced stainless steel. This can be addressed by appropriate surface modification techniques redefine the with required properties. characteristics of atmospheric plasma sprayed AlCoCrFeNi High Entropy Alloy (HEA) on SS316l are presented this study. coating characterisation revealed uniform homogeneous deposition gas-atomized HEA spanning for 150 µm. coated substrates were further annealed 2 h at 400 °C, 550 700 °C and 850 annealing offered enhanced microstructure. Annealing sample a 46% improvement microhardness against uncoated post-annealing. electrochemical tests showcased improved resistance after through formation protective oxide layer influence HEA. Hot 900 resulted 10.1%, 8.49%, 10.36% than pre 44.09%, 44.25%, 42.09% under three salt mixtures respectively. microstructural analysis examines various modes verifies presence layers.
