New Breakthrough in Gas Turbine Blade Repair Technology

Gas turbine blades are a core component of gas turbines, directly affecting the overall performance and efficiency. Due to prolonged operation under high-temperature, high-pressure, and high-speed conditions, blades are prone to damage such as wear, corrosion, and cracking.

New Repair Process

Recently, the industry has seen several breakthroughs in blade repair technologies, primarily including:

• Laser Cladding Repair: Uses a high-energy laser beam to melt alloy powder and deposit it onto damaged areas for precise repair with strong bonding.
• Cold Spray Repair: Uses high-velocity gas to accelerate metal powder, which impacts the substrate surface to form a coating. Offers minimal thermal impact and is ideal for superalloys.
• Composite Repair Process: Leverages the advantages of multiple repair techniques to implement the optimal solution for each damage type.

Economic Benefit Analysis

Adopting advanced repair technologies delivers significant economic benefits compared to traditional methods:

• Reduced repair costs by 30%-50%
• Extended component lifespan: 20%–40%
• Extend replacement cycles to reduce spare parts procurement costs.
• Reduce downtime, boost equipment utilization
