Corrosion initiation and propagation of nickel base alloys in severe sea water applications
- Cortest Labs. Limited, Sheffield (United Kingdom)
Nickel base alloys such as Alloy 625, C22, C276 and 59 are generally considered to have exceptional corrosion resistances in critical sea water applications at ambient temperature. Test results published in recent years however indicate that sever crevice corrosion of some of these alloys may occur under certain conditions. Exposure testes have been carried out in natural and chlorinated sea water on these alloys, together with two high N alloys, Alloy 24 and Alloy 654SMO. Electrochemical studies and simple mathematical mode.lling have also been carried out. These data, together with surface studies, help explain the observed phenomena and assist in the safe selection of alloys for critical sea water applications.
