Plasma Breakthroughs for Aerospace Bonding and Corrosion Prevention
Technical Presentation: A Cleaner, Stronger Bond
With the rapid expansion of composites in aerospace design and manufacturing, the industry is increasingly reliant on strong, durable, and environmentally safe bonding technologies. The presentation, titled “Enhanced Bond Strength and Corrosion Prevention in Composite and Metal Structures Through Plasma Modification,” highlights how atmospheric pressure plasma
jets improve adhesive bonding by increasing surface free energy (SFE) and enabling covalent bonding—without the damage, contamination, or environmental hazards associated with traditional surface treatments like grit blasting or chemical etching.
Plasmatreat’s Openair-Plasma® technology demonstrated a 40% improvement in lap shear strength on carbon fiber composites compared to untreated surfaces, and outperformed methods such as solvent wiping, hand sanding, and even laser ablation.
The presentation will also include new results from plasma-applied anticorrosion barrier coatings. Applied as a nanoscale tie layer to metallic substrates, this treatment blocks moisture ingress at the bond line — a critical factor for long-term durability in aerospace environments. Testing with copper sulfate solution confirmed strong corrosion resistance on aluminum samples.
Technology Spotlight: Aerospace-Scale Plasma Systems
At CAMX 2025, Plasmatreat will also showcase its low-pressure, large-capacity plasma systems, built for the aerospace industry’s most demanding applications. These systems are engineered for the pretreatment of large composite panels, sandwich structures, honeycomb cores, and other lightweight components commonly used in aircraft interiors, fuselage assemblies, and structural bonding.
Designed for both R&D and full-scale production, Plasmatreat’s low-pressure systems offer:
- High-uniformity plasma treatment in large vacuum chambers
- Consistent, repeatable surface activation
- Zero hazardous waste and compliance with sustainability initiatives
“Our goal is to give aerospace engineers a better bonding process—one that’s cleaner, more consistent, and aligned with the industry's move toward automation and sustainability,” said Hardev Grewal, President & CEO at Plasmatreat North America. “From atmospheric plasma jets for in-line prep to vacuum chambers that handle full-size, geometrically complex components, we’re delivering real-world solutions that improve performance and reliability.”
Visit Plasmatreat at Booth D56 – Live Demos, Technical Sessions & Surface Consulting
Plasmatreat will offer live plasma demonstrations, real-time surface consulting, and daily technical sessions at Booth D56. Each day at 11:30 AM, visitors are invited to attend a 30-minute technical session focused on plasma-based surface preparation, activation, and process qualification. These sessions will feature hands-on insights using the Brighton analytical tool, with a technical specialist from Brighton Science on hand to provide live data interpretation and expert guidance.
Plasmatreat will also offer on-the-spot surface consulting throughout the event. Visitors are encouraged to bring their own material samples for real-time analysis and personalized feedback from our technical team. This hands-on approach is designed to help manufacturers evaluate surface readiness, improve adhesion, reduce rework, and streamline bonding processes—right from the show floor.
We look forward to welcoming you to Booth D56 and showing how plasma technology can help protect your product—and the planet.
