Synergetic Heterophase and Selective Defect Engineering of Nano Multicomponent Alloys for Rechargeable Zn–Air Batteries

Carbon Energy, EarlyView.
An fcc/bcc with defects (bcc‐d) MCA is designed by utilizing the interplay between heterophase and selective defect engineering and exhibits excellent electrocatalytic activity suitable for high‐performance zinc–air batteries. The synergistic catalysis of the fcc/bcc‐d breaks the universal linear‐scaling relationships of adsorbed multi‐intermediates ...

Deposition of High-Entropy Alloy (HEA) coatings by HVOF and cold gas spray

Journal of Alloys and Compounds
High-entropy alloy (HEA) coatings were deposited by high-velocity oxygen fuel (HVOF) and cold gas spraying (CGS) using mechanically alloyed feedstock materials, as an alternative to conventional coatings such as Stellite. Cr-Mn-Fe-Co-Ni and Alx(Cr20Mn25Fe40Ni15)100-x (x =0, 10, 14) alloys were considered.
