Phase 1 SBIR

Agency: National Aeronautics and Space Administration
Topic: 10-1-A1.01
Budget: 01/01/11 - 12/31/11

Powder metal (PM) superalloys used for critical compressor and turbine disk applications are prone to fatigue failures in stress concentration features such as holes and radii, as well as from corrosion pits and inclusions. Residual stress and cold work will have a dramatic impact on the fatigue performance. Shot peening is widely used on PM dis...

Phase 1 SBIR

Agency: Air Force
Topic: AF02-113
Budget: 04/05/02 - 01/05/03

The 4th stage compressor IBR of the JSF F119 engine is fatigue limited. Surface enhancement, by the introduction of compressive residual stress, is a practical means of improving fatigue performance without changing material or design. Low Plasticity Burnishing (LPB) provides twice the HCF strength and four times the damage tolerance of shot p...

Phase 2 SBIR

Agency: Navy
Topic: N01-024
Budget: 03/14/02 - 03/14/04

Improved damage tolerance is critical to achieving reduced engine ownership costs and increasing safety and fleet readiness. In Phase I, low plasticity burnishing (LPB) was successfully demonstrated to improve the damage tolerance of the F404 1st stage fan blade by an order of magnitude through the introduction of high magnitude throu...

Phase 1 SBIR

Agency: Navy
Topic: N01-024
Budget: 05/18/01 - 11/18/01

Low Plasticity Burnishing (LPB) has been shown to provide twice the HCF strength of shot peening, and four times the strength after FOD in Ti-6Al-4V and IN718 laboratory specimens exposed to turbine engine temperatures. The deep compressive layer produced by LPB is comparable to laser shock peening (LSP), and can fully arrest the growth of 0...
