ACCOMPLISHMENTS Developed and demonstrated low plasticity burnishing

(LPB) as an affordable means of producing deep stable compression in metallic components Produced compressive layer essentially stable at engine operating temperatures by LPB LPB increases finite fatigue life by an order of magnitude, can double the endurance limit, and retard

existing cracks

COMMERCIALIZATION Lambda Research created Surface Enhancement Technologies, LLC to license, market, and provide LPB

Surface Enhancement Technologies employs 3 full time staff members

NASA SBIR laid the ground work for a SBIR with NAVAIR

GOVERNMENT/SCIENCE APPLICATIONS Important to NASA, the Military, and DOE for aircraft and

ground based turbines and aging aircraft. Because the compression doesn’t relax at high temperatures, LPB is extremely useful; hence, this should save money for the military by extending aircraft life

Demonstrated LPB on advanced disk superalloys, assisted by NASA Ultrasafe Propulsion Project
