A leading aircraft manufacturer faced challenges with long lead times and inconsistent residual stress results from their shot peening supplier. Lambda Technologies was tasked with replacing the shot peening process with Low Plasticity Burnishing (LPB®), maintaining identical coverage and compressive residual stress.

Replacing the shot peening process resulted in:

• Enhanced Efficiency: LPB reduces processing times and eliminates the need for masking or additional preparation steps.
• Improved Quality: LPB ensures consistent compressive residual stress with 100% coverage, contributing to greater reliability in critical components.

How do you improve the damage tolerance of a gas turbine blade without changing its design or material?

For 7FA R0 blades, Lambda Technologies used LPB® to introduce a deep, stable layer of compressive residual stress in the leading-edge region. The process was designed to match or exceed the compression achieved with laser peening while maintaining surface integrity and leaving an unblemished surface.

Explore the results in this Power Engineering article:

Low plasticity burnishing can be applied to new or existing R0 blades to extend component life while increasing reliability, confidence and margins of safety.

Threaded fasteners are often among the most highly stressed features in an assembly, making them common sites for fatigue crack initiation.

In this study, Lambda Research evaluated the effect of compressive residual stress on the fatigue performance of steel threads. The results demonstrated a significant improvement in fatigue life, highlighting the important role residual stress can play in extending the durability of threaded components.

LPB® is one of the few surface enhancement technologies that offers consistent, repeatable, quantifiable improvements.

Every LPB® application is validated through residual stress measurement and tailored to the geometry, material, and loading conditions of your component.

What do we typically measure?
• Depth and magnitude of residual compression
• Surface finish—from mirror-like to customer-specified Ra
• Microstructure
• Fatigue performance under real-world stress levels

Whether you’re tracking fatigue life, mitigating stress corrosion cracking, or eliminating fretting damage, LPB® delivers performance you can count on and replicate across parts, programs, and platforms.

When sustainability is discussed in manufacturing, the conversation usually focuses on energy consumption or materials.

Component life extension deserves a place in that discussion too.

Every time a critical component remains in service longer, fewer replacement parts need to be manufactured, shipped, inspected, and installed.

In industries like aerospace, power generation, and oil & gas, extending component life reduces costs while also reducing material consumption and waste.

Sometimes the most sustainable component is the one that doesn't need to be replaced.

This video case study shows how the use of engineered compressive residual stress mitigated erosion-induced fatigue in 7FA gas turbine R0 blades.

The rotor life of the 7FA gas turbine is about 144,000 hours or 5,000 starts. The primary life limiting factor is high cycle fatigue cracking at the leading ...
