📌 Data Centers Control Cabinet - Underfilm corrosion in submerged brackish water

Industry: Data Centers · Severity: Critical · Mechanism: Underfilm corrosion · Risk: 98/100

🧾 Summary

A control cabinet used in a data centers application shows underfilm corrosion risk after exposure to submerged brackish water. The design review focuses on material pairing, geometry, coating coverage, inspection access, and realistic validation testing.

⚠️ Design Risk

Likely weak points include local electrolyte retention, incompatible material pairing, coating discontinuities, trapped debris, and missing acceptance criteria for corrosion validation.

🛠️ Recommended Controls

Recommended controls: inspection hold point, sacrificial element review, and lubricant/contact finish change. Add drawing notes, supplier evidence requirements, and a validation plan that reflects the expected service environment.

🎓 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.
