Low Plasticity Burnishing

Lambda Technologies

Cincinnati, OH

INNOVATION
Low Plasticity Burnishing (LPB) improves the performance, strength, damage tolerance, and life span of metal components without changing either the material or the component design.

ACCOMPLISHMENTS
  • LPB has successfully eliminated fretting fatigue at the neck taper of hip implants, reducing the need for painful and costly follow-up surgeries due to implant fatigue failure.
  • LPB processing is done on basic CNC machines, allowing for easy integration into manufacturing and low start up costs.
  • It is estimated that LPB will save the aircraft market millions of dollars for the mitigation of stress corrosion cracking on just one landing gear application.
  • In 2010, LPB received an R&D 100 Award, which recognized this innovation as one of the most technologically significant new products of the year.
COMMERCIALIZATION
  • LPB is currently in use by the Delta Airlines, U.S. Steel, and orthopedic equipment manufacturers across the nation.
  • Current applications include: aircraft components, hip implants, and closure welds on nuclear waste containers.
  • Research is being performed to demonstrate LPB in manufacturing and repairing steam turbines, pipelines, and automotive components.
GOVERNMENT/SCIENCE APPLICATIONS
  • LPB is currently in use by the U.S. Navy, U.S. Air Force, and the U.S. Department of Energy.
  • LPB was chosen over all other technologies by the U.S. Department of Energy to strengthen closure welds on nuclear waste containers designed for the Yucca Mountain facility.
  • LPB has been applied to over 10,000 F402 engine vanes for the Naval Air Systems Command (NAVAIR), mitigating foreign object damage on the AV8-B Harrier.
  • NASA can use the LPB process to repair and modify aircraft components.
