Accelerated corrosion and premature failure of copper-nickel seawater piping has recently become a problem in naval ships operating in polluted seawater. From the outset, sulfide pollution was suspected as the cause of the unusually high corrosion rates. Sulfide levels as high as 0.27 mg/dm3 were reported in the vicinity of the naval ships,1  and it is well known2-11  that sulfide can be aggressive toward copper alloys.
