Thermal Nitridation Deoxygenation and Biotribological Properties of Zr2.5Nb

Biosurface and Biotribology, Volume 11, Issue 1, January/December 2025.
ABSTRACT Zirconium and its alloys are considered to be materials for artificial joints because of their excellent biocompatibility. In this study, we proposed the introduction of high‐purity iron beads as external deoxidisers to inhibit the oxidation of Zr2.5Nb during thermal nitriding and investigated the biotribological properties of this alloy after
