ABSTRACT
Ti–Nb alloys are considered highly promising for orthopedic applications due to their excellent functional properties, including superior biocompatibility and a low modulus of elasticity. Forming such intermetallic structures as thin films or coatings on advanced materials is particularly advantageous, as these materials are typically exposed to demanding service conditions. In this study, Ti–Nb coatings were fabricated on titanium substrates using an electron beam treatment technique. Initially, a 1 μm Nb layer was deposited on commerciallypure titanium via Direct Current (DC) Magnetron Sputtering. The samples were subsequently modified by a scanning electron beam, with beam power varied between 1000 and 2000 W. The resulting phase composition of the intermetallic structures was analyzed using X-ray diffraction (XRD). Their microstructure and chemical composition were characterized by Scanning Electron Microscopy (SEM) and Energy-Dispersive X-ray Spectroscopy (EDS), respectively. Mechanical performance was evaluated in terms of hardness, Young’s modulus, and Coefficient of Friction (COF). The results demonstrate that electron beam treatment enables the formation of Ti–Nb intermetallic coatings with enhanced mechanical and functional properties, making them promising candidates for biomedical and orthopedic applications. The potential integration of these coatings into implant manufacturing and modern biomedicine is discussed in detail.
