文物的不可再生性使得每件文物都显得珍贵,文物的修复保护就是为了将文物的价值最大程度发挥并保存下来。一般来说,各类文物按照质地的不同,都会有一套通行的修复保护方法。一般来说,文物修复分为文物的接收、记录现状,文物性能的检测工作,文物修复方案的制定,文物修复保护,填写修复档案并验收等步骤。铁质文物一般都要经过缓蚀、封护处理。古代铁器是铁和碳的合金,可分为三大类即铁素体、铁素体渗碳体、铁素体石墨体加少许渗碳体。它们的结构多带有微孔和腐蚀通道,铁器表面不同的金相组也会引起电化学腐蚀。并且铁元素本身化学性质较活泼,是一种强还原剂,这都是 The irreplaceability of cultural relics makes each piece of cultural relics precious, and the restoration and protection of cultural relics is to maximize the value of cultural relics and save them. In general, all kinds of cultural relics in accordance with the different texture, there will be a common method of restoration and protection. Generally speaking, cultural relics restoration is divided into the steps of receiving and recording cultural relics, testing the performance of cultural relics, formulating cultural relics, rehabilitating cultural relics, filling in and recovering archives, and so on. Iron artifacts generally have to go through corrosion and seal protection. Ancient iron is iron and carbon alloy can be divided into three categories that is ferrite, ferrite cementite, ferrite graphite plus a little cementite. Their structure is more with micro-pores and corrosion channels, different metal surface of the iron group can cause electrochemical corrosion. And iron itself chemical properties more lively, is a strong reducing agent, which are
