为了探讨九成宫出土铁器严重锈蚀的主要影响因素，为铁器文物研究设计科学有效的保护方法和最佳保存条件，采用X-衍射粉末法分析九成宫出土的11件铁器的锈蚀产物成分。分析结果表明，锈蚀产物的主要成分为α、β、γ三种不同构型的碱式氧化铁和Fe3O4。这是铁器铁碳合金成分Fe-C活性差异引起析氢、吸氧、差异充气等电化学腐蚀产生结构疏松，在九成宫特别潮湿环境中H2O、O2、空气中有害气体不断渗入，铁器粘附土层中溶盐及尘埃中酸、碱、盐溶于铁器表面水膜而进行长期贴附电化学腐蚀的结果。据此，研究设计出对锈蚀严重的出土铁器进行松土，缓蚀松土，络合法除沉积物，冷热交换法脱盐，最后进行缓蚀防腐加固及表面隔氧、防潮、防有害气体的表面封护保护方案。按此方案保护处理了17件锈蚀严重的铁器，保护效果很好，可以作为其它铁器文物保护的重要参考。

In order to get a clear understanding of the corrosion and the primary factor of iron objects unearthed from Tang Dynasty JiuCheng Palace Relic, XRD was used to analysize eleven iron objects. The XRD diagrams were given and the structures of all corrosion products were discussed. We found that the main ingredients were α,β, and γ FeOOH and Fe3O4. Combined with study on the corrosion mechanism of iron objects from Qin and Han Dynasties, we achieved a deeper understanding of the chemical and electrochemical mechanism of iron corrosion. After analyzing the six major corrosive factors, we concluded that the most important condition in iron object protection is the prevention of oxygen, water, and other detrimental gases. Based on our conclusion, we cleaned and surface -sealed 17 iron objects from the Relics to prevent their contact with oxygen, moisture, and other corrosive gases. So far all the objects were under good condition. Our method can be applied for general iron object protection.
