原始语种摘要: Abstract(#br)High-entropy alloy (HEA) coatings with near-equal molar ratio TiAlNiSiV were synthesized by laser cladding on a Ti-6Al-4 V alloy. The structure and composition of the HEA coating were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) on a microscope equipped with energy-dispersive spectroscopy (EDS). The results showed that the HEA coating mainly comprised (Ti,V) 5 Si 3 , NiAl and TiN. NiAl with the B2 structure was an ordered structure of BCC structure. (Ti,V) 5 Si 3 was generated by mutual dissolution of V 5 Si 3 and Ti 5 Si 3 . The phase composition was theoretically identified by the existing binary and ternary phase diagrams and the Gibbs energy of Ti 5 Si 3 and V 5 Si 3 . The hardness of the TiAlNiSiV HEA coating was 1151∼1357 HV, which was...
