Abstract
The corrosion behaviour of nanostructured Cu90Ni10 alloys in neutral soluti on containing different chloride concentrations has been investigated. The passivity of the alloy and the influence of the crystal structure have been examined. A critical chloride concentration for the passive behaviour of t he alloys has been determined. The comparison between nanostructured and co arse grained Cu90Ni10 alloys shows a decrease in the protective properties of the passive layer in the nanostructured alloy. Some possible reasons to explain this behaviour have been discussed. (C) 1999 Elsevier Science Ltd. All rights reserved.
