Structure of Ti-Ta Alloys Fabricated by Electron-beam Surface Alloying

In the present study, Ta coatings with a thickness of 1.7 and 4.2 μm were deposited on Ti samples through reactive magnetron sputtering. The are furthermore treated by scanning electron beam in order to form Ti-Ta surface alloy. A change phase composition alloy was observed X-ray diffraction (XRD). microstructure chemical studied via microscopy (SEM) energy-dispersive spectroscopy (EDX). results indicate that both cases alloyed zone remains same at about 50 μm. concentration increases increase pre-applied coating. sample coating has single-phase hexagonal closed packed structure, corresponding \(\alpha \) phase, whilst exhibits biphasic closed-packed structure body-centred cubic '\) martensitic β phases.
