๐ Marine Painted Steel Bracket - Uniform corrosion in warm humid plant air
Industry: Marine ยท Severity: Critical ยท Mechanism: Uniform corrosion ยท Risk: 88/100
๐งพ Summary
A painted steel bracket used in a marine application shows uniform corrosion risk after exposure to warm humid plant air. The design review focuses on material pairing, geometry, coating coverage, inspection access, and realistic validation testing.
โ ๏ธ Design Risk
Likely weak points include local electrolyte retention, incompatible material pairing, coating discontinuities, trapped debris, and missing acceptance criteria for corrosion validation.
๐ ๏ธ Recommended Controls
Recommended controls: lubricant/contact finish change, sealed joint geometry, and supplier process control. Add drawing notes, supplier evidence requirements, and a validation plan that reflects the expected service environment.
๐ Learning Notes
Learners should identify the corrosion mechanism, estimate severity, and decide whether prevention should come from material change, coating change, geometry change, sealing, isolation, or inspection planning.
