一、引言在众多的出土文物中,铁器也占有一定的比重,但铁器文物大多是铁和碳的合金,其主要成分铁的性质比较活泼,其机构多带有微孔和腐蚀通道,铁器表面不同的金相组织也会引起电化学腐蚀,因此铁器文物极易被锈蚀。很多铁器文物埋于地下年代久远,出土时已经腐蚀严重,甚至千疮百 I. INTRODUCTION In a large number of unearthed relics, ironware also occupies a certain proportion, but most of the iron artifacts are iron and carbon alloy, the main component of the nature of iron is more lively, and its body with microporous and corroded channels, the surface of the iron Different metallurgical structures also cause electrochemical corrosion, so iron artifacts can easily be corroded. A lot of iron artifacts buried underground for a long time, has been unearthed serious corrosion, and even riddled with
