Research team includes Micheal Kattoura, now an LSPT materials scientist
Laser peening can prevent or arrest failure of pipes and containment structures due to one of the most pernicious metal threats to nuclear components: Primary Water Stress Corrosion Cracking (PWSCC). That is the conclusion of a team of scientists from Purdue, the University of Cincinnati (UC) and Idaho National Laboratory, including Micheal Kattoura, then a Ph.D. candidate at UC and now a Materials Scientist at LSP Technologies, Inc. (LSPT).
Kattoura worked with an interdisciplinary team to publish their findings in the Journal of Nuclear Materials as “Effects of corrosion-inhibiting surface treatments on irradiated microstructure development in Ni-base alloy 718,” published online in early October (See abstract or access the full study at https://www.sciencedirect.com/science/article/pii/S0022311518309097 – download fees apply).
Laser Shock Peening (LSP) and UNSM work differently to prevent radiation damage.
“Radiation looks for ways to attack the structural integrity of metal parts, especially areas at or near the surface of the part,” Kattoura said.
“We call these point defects, and – depending on the type of metal – the radiation will make parts more brittle, softer or more vulnerable to corrosion and cracking. But by all the measures that we used in the experiments, laser peening provided substantial benefits to prevent damage to irradiated parts.”
The newly published research, though not sponsored by LSPT, adds to the strong rationale for providing laser peening equipment to the nuclear power industry , said David Lahrman, LSP Technologies VP of Business Development. (See LSP Technologies Wins Customers in New Markets.) “We’ve been supplying laser peening services to the power generation industry for many years, and this research is another indication of how much nuclear power operations can benefit from laser peening,” he said.
The new LSP Technologies headquarters at 6161 Shamrock Ct., Dublin, will provide more room for expanding staff and larger customer parts.
Larger facility to accommodate a growing workforce and larger customer components
LSP Technologies, Inc. (LSPT), the rapidly growing leader and innovator in laser peening services and equipment, has acquired a 65,000-square foot facility at 6161 Shamrock Ct., Dublin., Ohio. LSPT will continue serving customers during the transition from its current headquarters and plant at 6145 Scherers Place,
Dublin, only 1.2 miles away.
“We are delighted to remain in Dublin, our home base since the company began 20 years ago,” said Jeff Dulaney, LSPT President and CEO. “We appreciate the continuing support of Dublin city officials, who made the decision to stay in Dublin an easy one.” LSPT plans to transition to the new facility in early 2019.”
The move represents a signifcant expansion for LSPT. The new facility will support a growing workforce and provide the ability to handle larger customer components onsite. LSPT employs more than 50 full-time staff, which is more than twice the company’s workforce from 2017, including more than 35 engineers, technicians, designers and technical support staff added since May.
LSP Technologies uses modeling to improve fatigue life for mission-critical parts, saving time and money in application development
Laser Peening a performance valve spring creates a compressive residual stress (blue in this FEA simulation) on the exterior of the wire where the stresses are the highest.
LSP Technologies, Inc. provides laser peening services and equipment, protecting hard-working parts from threatening forces in real-world operating environments.
Using finite element analysis (FEA), we can pinpoint exactly how to use laser peening to prevent corrosion, cracking, foreign object damage and high-cycle fatigue.
We can’t change the laws of physics, but we can slow down the effects of vibration, temperature, friction and other factors that try to assault your metal components.
Laser Peening Systems can extend the fatigue life of parts by more than 20 times the expectations for untreated parts.
To obtain those results, we collaborate closely with our customers in a process encompassing precision modeling, precision targeting, and precision execution of a laser peening strategy to extend fatigue life.
FEA modeling can play a key role in the process, matching a precise understanding of customer components with the benefits of laser peening technology.

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?
LSP Technologies Inc.’s Micheal Kattoura, Materials Research Engineer, and Stan Bovid, Director of Materials Research, at the Los Alamos National Laboratory’s Proton Radiography conference in Santa Fe.
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.
Employees who joined LSP Technologies in the last two years now have input into key new initiatives.
