Low Plasticity Burnishing

Product From Lambda Technologies Group

Developed by Cincinnati-based Lambda Technologies, Low Plasticity Burnishing (LPB®) is a technique that mitigates SCC, increases fatigue strength and prevents FOD from causing crack formation. LPB uses designed residual compressive stress to enhance the fatigue strength and damage tolerance of aircraft components such as turbine blades, landing gear and structural members. The patented process works by rolling a high-hardness ball across the surface of the work piece to create beneficial compression. The depth and magnitude of compression are designed for the applied stresses and operating environment. The ball is supported by a constant volume flow of fluid, preventing any chance of dragging or damaging the component. LPB is performed using CNC machine tools or robots, allowing easy integration into production and maintenance facilities. Parts can be treated during manufacturing or after they have been in service. No alteration of the component’s material or design is required. Engineers are able to create a protective layer of compressive residual stress that is precisely the form, depth and magnitude required to offset applied tensile stresses in service, and mitigate cracking.

Low plasticity burnishing treatment

Product From Lambda Technologies Group

Low Plasticity Burnishing (LPB) applies a deep, stable layer of compression in high stress areas of components to extend their service life and improve performance. The patented process works by rolling a high-hardness ball across the surface of the work piece to create zones of beneficial compression. The depth, magnitude, and distribution of the protective zone is designed for the applied stresses, component geometry, and operating environment. The ball is supported by a constant volume flow of fluid, preventing any chance of dragging or damaging the component. LPB is performed using CNC machine tools or robots, making it easily fit into production and maintenance facilities. Parts can be treated during manufacturing or after they have been in service. No alteration of the component’s material or design is required. For more information visit
