Proton Radiography: real-time images for shock in metals

LSPT experts explore pRad potential for laser peening process

Can you make a movie to show the shock wave created by laser peening as it travels through metal? What would it tell you about how laser peening alters metal structures and adds to fatigue life?

While X-rays can’t show laser shock waves in real time due to the density of metals, scientists working in Proton Radiography, also referred to as pRad, can use protons to penetrate dense metals to find out more about how they react to shockwaves and explosions.

Los Alamos National Laboratory researchers invited two scientists from LSP Technologies, Inc. (LSPT) to learn more and contribute to the discussion at a workshop entitled “Proton Radiography (pRad) for Materials: Mesoscale and Beyond,” in Santa Fe, New Mexico, August 27-29.

Stan Bovid, LSPT Director of Materials Research, and Micheal Kattoura, LSPT Materials Research Engineer, attended  the symposium. The LSPT team discussed Laser-Driven Shockwaves in Materials, joining other experts in materials science, as well as specialists in additive manufacturing, proton radiography, shock physics, and mining.

LSP Technologies’ Portable Laser Peening System combats metal fatigue in hard-to-reach parts

The laser source for the Portable Laser Peening System provides adaptability for fiber optic transmission of the laser beam, as well as a smaller size.

The laser source for the Portable Laser Peening System provides adaptability for fiber optic transmission of the laser beam, as well as a smaller size — less than a meter long.

Fiber optics and custom tools will carry miniaturized laser peening technology to mission-critical components

Dublin, Ohio – August 6, 2018 – LSP Technologies is designing a new portable fiber-optic laser peening system to improve fatigue life and prevent cracking and corrosion for small, hard-to-reach parts in new applications.

The Portable Laser Peening System will include miniature mirrors, lenses, and water injection/extraction mechanisms for complex maintenance, repair, and manufacturing environments. This means the portable system will deliver effective laser peening with lower energy, higher pulse rates, and the maneuverability of fiber optics.

LSP Technologies wins customers in new markets

The Procudo® 200 Laser Peening System has a compact layout.

The Procudo® 200 Laser Peening System has a compact layout. Embedded laser optics fit easily on a 4’x6′ optical table.

Dublin, Ohio – LSP Technologies, Inc. (LSPT) is launching new applications for its patented Laser Peening Process to serve the nuclear power, heavy equipment, and aircraft maintenance industries.

Precision, portability, and cost-effectiveness help open markets for the Procudo® Laser Peening System

New customers are adopting LSPT’s Procudo® Laser Peening Systems due to their precision, flexibility, low cost, and higher throughput rates, said President and CEO Jeff Dulaney.

LSPT’s patented Laser Peening Systems use a pulsed shock wave from high-energy lasers to enhance the ability of parts to resist foreign object damage (FOD), stress corrosion, and metal cracking.

“Our Laser Peening Systems increase the service life of many metal components by 10-20 times,” Dulaney said. LSPT’s metal stress modeling identifies stress points and enables precisely calibrated laser pulses for fatigue life improvement without damaging metal surfaces the way shot peening usually does, he said.

“The Procudo® Laser Peening System is the only commercially available laser peening equipment capable of a wide variety of customer applications,” he explained. “We can install the equipment in customer manufacturing and maintenance facilities.”

LSP Technologies Materials Research Engineer Micheal Kattoura

LSP Technologies, Inc.’s Micheal Kattoura presented findings on the stabilizing effects of laser peening for metal parts subject to high-temperature conditions at the 18th International Conference on the Strength of Metals (www.icsma18.org) July 16 at The Ohio State University’s Ohio Union.

Kattoura serves as a Materials Research Engineer for LSP Technologies (LSPT), providing expertise in both materials science and applied mechanics to quantify metal improvement benefits from LSPT’s laser peening systems in a variety of commercial applications.

“My research on this project underscored the benefits of the laser peening process for metal fatigue strength, even at elevated operational temperatures of 650℃ , or 1,200℉,” Kattoura said. “Metals we laser peened and tested at these elevated temperatures were able to retain a large amount of residual compressive stresses and stable microstructure created by the laser peening process.”

The installation of LSP Technology’s Procudo® Laser Peening System at the ZAL TechCenter in Hamburg, Germany, became the cover story for the July 2018 issue of Metal Finishing News (MFN). The magazine highlighted the many applications of Laser Peening ZAL hopes to explore for the aerospace industry, collaborating with Airbus Industries, Lufthansa and LSP Technologies. Here is MFN’s original version in PDF format.  

The aerospace industry has been driving innovation since the earliest days of flight. It takes a lot to defy gravity, to soar across oceans or eclipse the speed of sound. It takes research and foresight, confidence and cunning, a commitment to solving problems and anticipating risk. This mentality has defined aviation for generations, and some of humanity’s great advancements came from our quest to conquer the clouds.
