TiNb Powder: The Ultimate Guide for 2025

Översikt

TiNb powder är en high-performance titanium-niobium alloy känd för sin exceptional biocompatibility, corrosion resistance, and mechanical properties. This alloy is widely used in medical implants, aerospace applications, and additive manufacturing (3D printing) på grund av dess low elastic modulus, high strength, and superior wear resistance.

This alloy consists of Titanium (Ti) as the base element with varying amounts of Niobium (Nb), typically ranging from 20% to 50% Nb, depending on the specific application. The absence of aluminum and vanadium makes it a superior alternative to Ti-6Al-4V for biomedical and high-performance applications.

• TiNb wire is fed into a high-energy plasma torch, melting it into fine droplets that form highly spherical powder particles.

Fördelar:
✔ Perfect spherical shape, ensuring superior flowability in powder bed fusion processes
✔ Ultrahög renhetvilket gör den idealisk för biomedical and high-performance aerospace applications
✔ Minimal satellite particles, leading to superior print quality

Nackdelar:
✖ Higher production costs
✖ Limited scalability for large-scale production

Best for: High-performance biomedical implants and aerospace components

3. PREP (Plasma Rotating Electrode Process)

Process:

• A rotating TiNb electrode is melted by plasma, while centrifugal force atomizes the molten material into fine spherical particles.

Fördelar:
✔ Ultrahög renhet, with minimal contamination
✔ Mycket sfärisk morfologi, leading to excellent flowability
✔ Minimal porosityvilket gör den idealisk för high-performance biomedical applications

Nackdelar:
✖ Very high cost
✖ Limited scalability
