Corrosion tests conducted in inhibited 60% LiBr indicate that liquid phase corrosion rates remain low even up to 350 F. However, vapor phase and liquid-vapor interface corrosion rates are such that carbon steel will require protection above 300 F. 70-30 cupro-nickel showed low corrosion rates with no pitting at all temperatures tested. Grade 2 titanium showed significant pitting at all temperatures tested. Grade 7 titanium showed significant pitting at 300 F and above. Fluoroshield, a fluorocarbon polymer coating, performed well in these tests and appears to be a viable method for protecting carbon steel in LiBr environments.
