Microstructure and Properties of an FeCoCrAlCu HEA Coating Synthesized via the Induction Remelting Method
نویسندگان
چکیده
An FeCoCrAlCu HEA coating was prepared on the surface of 45# steel by cold-spray-assisted induction remelting. The results showed that composed BCC and FCC phases. phase possessed an amplitude-modulated structure consisting a B1-disordered (FeCr) B2-ordered (AlCo), as well nanoscale precipitated near grain boundaries. solid solution Al–Cu matrix manifested characteristics typical twin structure. In addition, hardness 528.2 HV. friction coefficient HEA-/Al2O3 pair 0.379, wear rate 3.96 × 10−5 mm3/(N m). 3.5 wt.%NaCl 5.0 wt.%H2SO4 corrosive media, had more positive self-corrosion potential (Ecorr) lower corrosion current density (Icorr) than substrate.
