【摘要】：夏饷铺墓地出土青铜器对探讨西周时期古鄂国的历史具有非常重要的意义,然而其表面普遍存在各种类型的腐蚀,妥善保存是开展科学研究的前提。基于此,利用pH计、超景深三维视频显微镜、拉曼光谱(Raman)及金相显微镜等分析方法,对此批器物的腐蚀环境及产物进行了分析。研究结果表明:该墓群出土青铜器优先腐蚀富铜相,富锡相较为稳定,因而抗腐蚀能力强,整体保存情况较好。相对先进的冷加工退火处理技术,致密的锈蚀分层,中性、贫氯的埋藏环境,是其保存情况较好的主要原因。其锈蚀产物多为无害锈,但是性质较为活泼的PbO在锈蚀产物中占有一定比例,因而在进行保护时应使用机械方法除去青铜器表面附着的土锈及PbO,使其保存于干燥、缺氧的环境中,且应避免与氯化物、硫化物、氢氧化物等腐蚀性较强的物质接触。
[Abstract]:The bronze ware unearthed in Xixiangpu cemetery is of great significance to the exploration of the history of ancient Hubei in the Western Zhou Dynasty. However, there are various kinds of corrosion on its surface, and proper preservation is the prerequisite for scientific research. Based on this, the corrosion environment and the products of these products were analyzed by using pH meter, 3D video microscope, Raman spectrum and metallographic microscope. The results show that the bronze wares unearthed in the tomb preferentially corrode the copper-rich phase, and the rich tin phase is relatively stable, so it has strong corrosion resistance and good overall preservation. The relatively advanced cold working annealing technology, dense corrosion stratification, neutral and chlorine poor burial environment are the main reasons for its better preservation. Most of the rust products are harmless rust, but the active PbO occupies a certain proportion in the rust products. Therefore, mechanical methods should be used to remove the rust and PBO attached to the surface of the bronze ware so that they can be preserved in the drying process. Avoid contact with corrosive substances such as chloride, sulphide and hydroxide in anoxic environment.
