At Westover, we demonstrated that localized anodizing can be restored directly on the C-5, giving maintainers a practical alternative to removing components for repair.”
TYRONE, GA, UNITED STATES, October 20, 2026 /EINPresswire.com/ -- Bring the repair to the aircraft, not the aircraft to the repair— Siva Palani, CTO of Corrdesa LLC
On September 2, 2026, Corrdesa delivered a Volta system to Westover Air Reserve Base, Massachusetts, to support localized sulfuric acid anodizing (SAA) restoration on C-5 cargo-floor repairs. Eight Westover maintainers completed two days of hands-on training, then used the system to restore the anodized finish around four C-5 structural patch repairs.
Structural patch repairs on C-5 cargo floors remove the original anodized protection from the surrounding aluminum. While chemical conversion coatings are commonly used for touch-up, these surfaces must withstand repeated foot and cargo traffic. Conventional off-aircraft treatment can also introduce additional disassembly and maintenance turnaround time.
What Is Volta?
Volta is part of Corrdesa’s family of mobile, non-drip corrosion remediation systems. It enables same-day, on-aircraft corrosion remediation at the operating-unit level without removing or disassembling aircraft components.
Following a structural patch repair, Volta can be used to restore the anodic oxide coating removed from the surrounding aluminum. Using localized sulfuric acid anodizing (SAA, MIL-A-8625 Type II), the system rebuilds that protective layer directly on the aircraft. Its patented 2 × 3-inch non-drip tools control the electrolyte during treatment, allowing technicians to process localized areas without electrolyte leakage.
By eliminating the need to remove components and send them off-aircraft for treatment, Volta can reduce treatment turnaround time and support greater mission readiness.
Repair at the point of need means less disassembly, less downtime, keeping readiness at the unit
A structural patch repair removes the original anodized finish from the surrounding aluminum. Under current touch-up practice, the exposed area is typically protected with a chemical conversion coating (MIL-DTL-5541). Volta instead restores the anodic coating through localized SAA, providing a protective layer closer to the original anodized condition than a conversion coating.
Corrdesa testing shows that localized SAA produced via the Volta process yields a hardness that matches or exceeds the aircraft's original floor anodize and outperforms chemical conversion coatings in corrosion and wear resistance. That difference matters on a C-5 cargo floor, where protective surfaces are subjected to repeated foot and cargo traffic.
Volta also brings the treatment process directly to the flight line. Its mobile design supports globally deployed, operational environments, allowing trained maintainers to perform the treatment using approved, established procedures and reducing dependence on centralized processing or repair facilities.
Training Westover Maintainers
The Westover deployment included two days of hands-on training for eight maintainers. Training covered system operation, process setup, tool handling, chemical safety, and proper PPE use. Each maintainer received the Volta Operational Manual and a certificate of completion.
Following the training, the Westover team put the system to work on actual C-5 cargo-floor repairs.
Post-training feedback consistently identified hands-on use of the equipment as the most valuable part of the training, with Corrdesa’s trainers described as helpful, patient, and thorough.
Putting Volta to Work
During the training, Westover maintainers used Volta to restore SAA on exposed aluminum around four C-5 cargo-floor structural patch repairs.
For one representative treatment, approximately 80 in² (516cm2) of exposed aluminum was re-anodized. The anodizing step took approximately 25 minutes; the complete process, including setup, took approximately 37 minutes. The repair anodic coating averaged 7.7 µm (0.3 mil) and was sealed with a more environmentally friendly trivalent-chromium post-sealing, without any electrolyte leakage.
80 in² → 7.7 µm Type II SAA, sealed in ~25 minutes
Expanding Volta's Flight-Line Applications
Already fielded on the U.S. Navy's P-8 program, Volta is now extending its applications to C-5 cargo-floor sustainment.
The Westover deployment marks Volta's first unit-level, flight-line deployment on the C-5 at an Air Force Reserve wing, placing localized anodizing capability directly in the hands of trained aircraft maintainers.
Volta is built around that idea: bring the repair to the aircraft, not the aircraft to the repair.
