Abstract Iron archaeological nails (16th century) were used as representative of the mild steel structures envisaged for the storage of nuclear waste. The influence of sulfide species on the corrosion behavior of the nails was investigated via the thorough description of the modifications undergone by the corrosion products surrounding the metal after re-immersion in deaerated sulfide solution. The only observed modification was the formation of FeS at the corrosion product layer/soil interface. The corrosion product layer, mainly composed of FeCO 3 , acts as protective barrier, the reactivity of FeCO 3 preventing sulfide species to reach the metal and influence the corrosion process.

先前形成的腐蚀产物层对土壤中铁考古文物的硫化物辅助腐蚀的作用

摘要 铁考古钉（16 世纪）被用作为储存核废料而设想的低碳钢结构的代表。通过对重新浸入脱气硫化物溶液后金属周围腐蚀产物所发生的变化的彻底描述，研究了硫化物种类对钉子腐蚀行为的影响。唯一观察到的变化是在腐蚀产物层/土壤界面处形成 FeS。主要由FeCO 3 组成的腐蚀产物层充当保护屏障，FeCO 3 的反应性阻止硫化物物质到达金属并影响腐蚀过程。
