Improve your quality control practices with Process Control Testing (PCT). Maintaining rigorous quality standards throughout the manufacturing process is critical in every industry. Multiple processes impart residual stresses throughout manufacturing, such as forging, heat treatment, and surface enhancement processes like shot peening or low plasticity burnishing. Accurate assessment, control, and management of these imparted stresses is crucial to ensuring the reliability of fatigue critical components. That's where our PCT comes in. With PCT, we monitor and test the residual stress levels in production parts at regular intervals. This ensures that parts consistently meet design performance requirements. Our informative brochure goes more in-depth with benefits and application examples. https://bit.ly/3FOgDca #QualityControl #manufacturing

We developed a solution to extend the fatigue life and improve the damage tolerance of the R0 blades. Using low plasticity burnishing (LPB®), Lambda Technologies engineers applied a deep, stable layer of engineered compression to the leading-edge region of the blades. This approach was designed to match or exceed the compression achieved with laser peening, while enhancing damage tolerance, maintaining surface integrity, and leaving an unblemished surface.

Nuclear power is a practical source of energy capable of meeting the world's requirements. However, it requires long-term storage solutions for hazardous materials created in production. Despite being made of corrosion-resistant Alloy-22, stress corrosion cracking has plagued nuclear waste containers, impacting design life, safety, and cost. When waste containers are welded shut, shrinkage during cooling causes high tensile stresses, leaving the welds in tension and vulnerable to stress corrosion cracking. Though they are designed to last for over 10,000 years, the combination of tension and stress corrosion cracking pose a significant threat of containment failure. Lambda developed a solution to completely eliminate stress corrosion cracking in the closure welds, ensuring waste containers could last for the entire designed component life.

The CFM56 family of aircraft engines power more than 13,400 commercial and military aircraft worldwide. However, historical maintenance data on the CFM56-7 series shows a tendency for fretting-induced microcracking in the dovetail edge of the first-stage high-pressure compressor (HPC) blade, posing a significant safety concern. We developed a solution that eliminates the chance of failure from fretting fatigue in CFM56 dovetails with low plasticity burnishing. Low plasticity burnishing is highly desirable in turbine applications due to the low cold work it produces. Lower cold work provides more stability to imparted stresses when exposed to things like high temperatures or repetitive loading that would normally cause relaxation.

Optimizing surface enhancement processes can lead to significant savings in time, resources, and overall production costs. All surface enhancement techniques can be optimized, but it's most common with shot peening. Dr. John Cammet and Dr. N. Jayaraman’s article for The Shot Peener explores when and how to optimize shot peening, challenging conventional wisdom and revealing the benefits you can expect.
