Figure 12. Representative BCC-B2 phase architecture and interfacial microstructure of a laser-deposited AlCoCrFeNiTi_0.5 HEA coating on Ti6Al4V. (A and B) XRD patterns of the Ti6Al4V substrate and as-deposited HEA coating, respectively; (C) coating/substrate interfacial morphology; (D) EDS line-scan profile across the HEA/Ti6Al4V interface; (E and F) SEM microstructures showing A2/B2 phase partitioning in the HEA coating.
