Corrosion resistance of niobium titanium capillary under different environmental conditions

The corrosion resistance of niobium titanium capillary shows strong stability under different environmental conditions, as follows:
• In biomedical environments, the passivation film formed on the surface of titanium alloys (including niobium titanium alloys) can effectively resist corrosion, reduce the release of metal ions, and avoid adverse biological reactions, thereby ensuring the long-term stability of implants and medical devices.
• In high-temperature melting environments, the corrosion resistance of niobium titanium alloys is subject to the interface reaction with ceramic crucible materials. Studies have shown that by optimizing the surface micro-nano structure and doping elements (such as ZrO2, Y2O3, etc.) of ceramic crucibles, the corrosion resistance of the crucible can be significantly improved, thereby ensuring the purity of the material and the life of the crucible during the melting of titanium alloys.
• In corrosive media, titanium alloys show excellent corrosion resistance, especially in marine and chemical environments. Due to their stable surface oxide film, they can resist corrosion from a variety of acids, alkalis, and salts, extending their service life.
• In reinforced composite materials, such as graphene reinforced titanium composite materials, the dispersion strengthening of graphene not only improves the mechanical properties, but also further improves the corrosion resistance. The corrosion potential and corrosion current density are better than pure titanium.
In summary, niobium titanium capillaries show good corrosion resistance in different environments, especially in biomedicine, high-temperature smelting and corrosive chemical environments. Through surface passivation film and material modification technology, its corrosion resistance is effectively improved, ensuring its long-term stable use.
