Working Title: The effect of metallurgical structure on the chloride-induced corrosion of archaeological wrought iron.
The contribution of chloride salts to the corrosion and destruction of archaeological wrought iron artefacts has been well documented in the archaeological conservation literature. The effect of metallurgical structure and composition on the chloride-induced corrosion of wrought iron is less well understood. The metallurgy of iron is readily evaluated and may have important implications for its post-excavation preservation, particularly when the artefacts to be preserved are numerous or very large and complete removal of chloride is practically difficult.
The aim of this study is to study the metallurgy of a large number of wrought iron archaeological artefacts and examine relationships with their chloride content and distribution, as well as post-excavation and post-treatment corrosion. The data obtained will inform practical decisions for preserving historic iron artefacts either by chloride extraction or by environmental control.
