Salt Spray & Galvanic Corrosion
Sea mist deposits chloride around the clock. Bare zinc or thin plating pits in weeks and contacts oxidize, so resistance climbs and joints run hot.
- 48 h NSS per IEC 60068-2-11 / GB/T 2423.17 — no red rust, white corrosion under 5%
- Shells in zinc alloy with 12 µm electroless nickel, or nickel-plated brass; stainless option for permanent moorings
- Contacts: 3 µm gold over 2 µm nickel — under 5 mΩ initial, under 10 mΩ after spray
- Field record: fishing-boat deck harness after two seasons — wipe, remate, still under 8 mΩ
