The erosion-corrosion behavior of nickel-based (UNS NO 6022) and copperbased (UNS C71500) alloy tubes in warm flowing seawater containing sulfide ions is investigated. Visual, optical and scanning electron microscopy examinations of the internal surfaces of the tubes were conducted to compare the susceptibilities to erosion-corrosion attack of these two alloys, taking into consideration the nature of the product films formed.
