Long-term alteration processes of iron fasteners extracted from archaeological shipwrecks aged in biologically active waterlogged media
Abstract
Waterlogged woods and iron reinforcements extracted from archaeological shipwrecks were studied. The corrosion mechanisms of the reinforcements were investigated by analyzing the corrosion products using a multi-technique approach. The woods contained pyrite and greigite. The reinforcements showing different degradation states were corroded into siderite, chukanovite, mackinawite, pyrite and greigite. Then, two half-nails were soaked in neutral and acidic Na2S solutions. Mackinawite precipitated only in neutral conditions. Through this study, the natural mackinawite-to-pyrite evolution process induced by a long-term exposure to sulfides is highlighted. This work also shows that iron sulfides can result from complex processes implying other sulfide-sensitive phases.
