Mitigating foreign object damage (FOD) in turbine engine blades was one of the first commercial applications of laser peening. In the early 1990s, the U.S. Air Force needed a powerful surface enhancement solution to address fatigue cracking in the F101 engines on the B-1 bomber.
In this live webinar highlight, LSPT Director of Research David Sokol tells the story of a landmark study comparing laser peening with shot peening for FOD prevention in titanium compressor blades. The superior performance of laser peened blades astounded the Air Force and gave birth to a new metal improvement industry.
