Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Ti‐15Mo‐2.5Ag alloy exhibited a low modulus and strong antibacterial ability but poor bioactivity. To resolve this problem, sandblasting and anodization were used to create a hydrophilic and nano‐Ag2O‐containing TiO2 coating. Subsequently, the microstructure and physicochemical properties were investigated by scanning electron microscopy, X ...
