Tunable mechanical, corrosion, and antimicrobial performance in multifunctional Cux‑Cr-Fe-Mn-Ni high-entropy alloys and E-beam coatings (opens in new tab)

Cux-Cr-Fe-Mn-Ni high-entropy alloys and their electron-beam-deposited coatings demonstrate a tunable balance of mechanical strength, corrosion resistance, and antimicrobial performance, offering a new paradigm for multifunctional protective materials. Dense nanocrystalline coatings with complex phase coexistence achieved exceptional hardness (~ 9.4 GPa) and a high elastic strain-to-failure ratio (H/E ≈ 0.05), indicating potential for improved resistance to wear and contact damage.
