本文旨在展示考古金属文物的原始表面可以在腐蚀产物中保存的不同方法。根据腐蚀机理，可以通过一些可用作线索的特征来定位原始表面。这些特征包括腐蚀产物中残留的金相组织、来自土壤或原始合金的元素含量以及在某些腐蚀界面处出现的解理。此外，腐蚀层的一些特征可以与腐蚀过程刚开始时发生的情况进行比较，尽管关于非常长期的腐蚀机制的知识存在相对差距。
This paper aims to show different ways the original surface of archaeological metal artefacts can be preserved in the corrosion products. Depending on the corrosion mechanism, the original surface can be located owing to some features that can be used as clues. These feature include the remains of metallurgical structure fossilised in the corrosion products, the content of elements either coming from the soil or from the original alloy, and cleavage occurring at some corrosion interface. Moreover, some of the features of the corrosion layers can be compared with what happens at the very beginning of the corrosion process despite a relative gap in knowledge as regards the very long term corrosion mechanisms.
