秭归出土东周时期铁剑的保护处理

三峡秭归出土东周铁剑，通过宏观结构、金相组织、电子探针、Ｘ射线衍射等多种方法分析，得出结论是，铁剑属于人工冶铁而非自然陨铁，采用冶炼铁锻打制作工艺制成。根据铁剑出土的自身状态，拟定保护方案是，采用高分子材料加固封护，保持其原有的外观，所用的材料具有使用期长、室温能聚合、无生霉等特点。处理后的铁剑达到文物铁器保护的要求。

PROTECTION AND TREATMENT OF THE EASTERN ZHOU IRON SWORD UNEARTHED IN ZIGUI COUNTY

By means of macrostructure examination, metallography, electronic probe and X ray diffraction analyses etc, it is concluded that the Eastern Zhou iron sword unearthed in Zigui, in the Yangtze Gorges is a kind of man made smelted iron, but not natural meteoric iron. The manufacturing technology of the sword was forging from wrought iron According to the condition of the unearthed sword, a protective method has been worked out. Polymer mate rials were used to consolidate, seal up, protect and preserve the original outward appearance of the sword. The adopted materials have three advantages: long term used, polymerizing at room temperature and moldiless. The sword after the treatment can accord with the demands of the preservation of iron culture relics.
