CORROSION RESISTANCE AND DURABILITY OF MATERIALS FOR OVERHEAD EQUIPMENT IN THE UNDERSEA TUNNEL

Overhead electrical contact systems experience corrosion, along with other service-induced damage. Causes for the corrosion of trolley wire and metal fittings were determined in the course of a 7-year test in a tunnel environment and also in an industrial atmosphere. Specimens included wire strands; metal fittings; their combinations; specimens of metal alloys for corrosion and fatigue tests; polymeric materials; and paint-coated specimens.
