ABSTRACT
Titanium–tantalum (Ti–Ta) alloys combine low density, and biocompatibility of titanium with the exceptional corrosion and oxidation resistance of tantalum. In bulk form, these alloys offer high mechanical strength, good fatigue performance, low elastic modulus, and excellent resistance to aggressive environments, making them suitable for a number of biomedical and chemical applications. When applied as coatings, Ti–Ta provides protective surface layers that enhance corrosion and wear resistance, improve thermal stability, and promote strong biological integration—all without replacing the base material. This makes Ti–Ta coatings a costeffective strategy to functionalize components for demanding environments while maintaining structural integrity. It is well known that the electron beam surface modification technique has a number of advantages in terms of the fabrication of surface structures and coatings. It enables precise, localized treatment with excellent control over depth and microstructure; improves surface properties and can refine or homogenize surface layers through rapid melting and solidification. Additionally, the process is clean, energy-efficient, and compatible with complex geometries, making it ideal for enhancing the performance of modern biomaterials. This article aims to provide a short overview on the possibilities for the fabrication of Ti-Ta coatings by the electron beam surface modification technique.
