Buoyancy Aerospace launches thin-film sulphuric anodising line, setting a new benchmark in process control and scalability

Buoyancy Aerospace announced the launch of its Thin-Film Sulphuric Acid Anodising (TFSAA) treatment line (MIL-A-8625 Type IIB), a production-ready capability engineered for aerospace and defence manufacturing.

The line is fully automated with a custom-developed PLC that provides deterministic, high-resolution control at the tank level. The system has been validated through 100+ fault-injection scenarios to deliver fast, predictable responses. Since entering commercial production, Buoyancy Aerospace has reported no out-of-spec process-control events to date.

Unlike conventional lines relying on single-tier shut-offs, the installation combines power isolation (circuit breakers), multi-sensor detection (smoke and heat), and automatic suppression, designed in accordance with RISCAuthority RC45 guidance for electroplating fire safety; integrated advanced monitoring supports operator situational awareness.

"This investment de-risks customer programmes by embedding resilience and upgrade paths directly into our processes for sovereign defence manufacturing," said Dr. Deepak Asokan, UK Head of Operations.

Why it matters

End-to-End Solution: Integrated with Non-Destructive Testing (e.g., UT, PT, MT, ET and radiography as specified) and a modern paint facility qualified for aerospace coatings, including fracture-critical components where specified.

Future-Ready Capability: Cr(VI)-free chemistries including TCS/PACS for conversion and post-seal, together with digital traceability via the company's MES/QMS, enable rapid scaling and upgrades with minimal disruption.

"This is a safety-integrated, scalable treatment capability for critical aerospace components," said Daniel Hutta, UK Head of Quality, Compliance, Health & Safety at Buoyancy Aerospace, who led the cross-functional programme.
