Abstract:
Twenty failure analysis caused by corrosion in copper and copper alloys heat exchangers were accomplished at Corrosion and Electrodeposition Laboratory of IPT between 1968 and 1988. This work is a review of these failures, the types of failure and their causes being described. The prevailing failures were by stress corrosion, pitting corrosion, erosion-corrosion and dezincification, the latter almost always being associated to stress corrosion.
