Corrosion Prevention

• Materials - Noble or close on series
• Where dissimilar metals in contact, more anodic metal should constitute larger surface area
• Protective coatings
• Environment - pH, de-aeration
• Cathodic Protection - Sacrificial anode
• Detail design - eg, avoidance of crevices, draining
• Vehicles: ventilation to minimise moisture
