Behaviour of 90–10 cupronickel in sea water

Abstract

During the past 50 years, the 90–10 iron modified cupronickel alloy (CA706) has been developed extensively for marine and offshore applications. It has proved to have good corrosion, erosion–corrosion, and fouling resistance to sea water. The behaviour and protection mechanism of the alloy in these environments has been the subject of many detailed studies under various conditions, i.e. differing flow velocities, temperatures, pH values, compositions of sea water, and many other factors. This review has been compiled by consulting hundreds of references on the properties and behaviour of this alloy. It provides a sufficient and unique guide for materials specialists, corrosion technologists, and engineers in the evaluation and use of this alloy in marine environments: it is fully referenced to allow a quick access to the relevant literature.
