Investigation of the accelerated corrosion of cupro-nickel piping

Abstract

The accelerated corrosion (erosion) of 70/30 cupro-nickel alloy was investigated as a function of environment using a laboratory recirculation loop. The environments utilized were unpolluted artificial sea water and artificial sea water polluted with sulfides (Na2S) and two different levels of ammonium ion (NH^Cl) . The use of ferrous sulfate (FeSO,) as an inhibitor was also briefly examined.
