Primary advantages of using TA15 titanium alloy in LENS printing for aerospace

High-Temperature Performance

TA15 (Ti-6.5Al-1Mo-1V-2Zr) titanium alloy offers superior high-temperature mechanical stability compared to standard Ti-6Al-4V, making it particularly suitable for aerospace engine components and thermal-structural parts. When applied through LENS repair or additive buildup, TA15 maintains strength and creep resistance in elevated temperature environments typical of aerospace and aviation systems.

Excellent Weldability and Deposition Quality

TA15 demonstrates stable melt pool behavior with reduced cracking tendency during LENS deposition. Its enhanced weldability allows additive feature build-up, localized reinforcement, or repair on components originally produced by vacuum investment casting or forging. This enables direct component restoration instead of full replacement.

Lightweight and High Strength Balance

The alloy features a high strength-to-weight ratio and improved fatigue resistance, allowing weight reduction without compromising safety-critical performance. Combined with post-processes such as hot isostatic pressing (HIP) and precision CNC machining, TA15 achieves aerospace-grade microstructure uniformity and dimensional accuracy.

Repair and Life Extension Capability

LENS printing enables in-situ repair of high-value TA15 components, especially in structural or engine-related applications. Instead of manufacturing new parts, worn or damaged regions can be rebuilt, reducing maintenance cost and downtime. This approach is widely used across power generation and military and defense sectors as well.

Compatibility With Advanced Processes

TA15 is highly responsive to post-treatment techniques. Heat treatment enhances microstructural refinement and fatigue resistance, while HIP ensures pore elimination and full density. For final precision, CNC machining ensures assembly-ready dimensional tolerance.
