为研究浙江温州瓯海M24墓出土的一件青铜器的腐蚀成因,采用扫描电镜(SEM)、X-射线荧光光谱仪(XRF)、X-射线衍射仪(XRD)、离子色谱分析仪(HPIC)等,对青铜剑腐蚀产物及其埋藏土壤进行了分析。结果表明,青铜剑已严重腐蚀,铜元素大量流失形成以锡元素为主的腐蚀产物。通过测量模拟瓯海土壤环境下的自腐蚀电位并参照Cu-H2O体系的电位-pH图,推导出了浙江瓯海出土一件西周青铜器腐蚀反应历程。研究结果对类似出土文物有参考价值。
為研究浙江溫州甌海M24墓齣土的一件青銅器的腐蝕成因,採用掃描電鏡(SEM)、X-射線熒光光譜儀(XRF)、X-射線衍射儀(XRD)、離子色譜分析儀(HPIC)等,對青銅劍腐蝕產物及其埋藏土壤進行瞭分析。結果錶明,青銅劍已嚴重腐蝕,銅元素大量流失形成以錫元素為主的腐蝕產物。通過測量模擬甌海土壤環境下的自腐蝕電位併參照Cu-H2O體繫的電位-pH圖,推導齣瞭浙江甌海齣土一件西週青銅器腐蝕反應歷程。研究結果對類似齣土文物有參攷價值。

To understand the formation of corrosion on a Western Zhou Dynasty bronze excavated from tomb M24 in Ouhai, Zhejiang province, scanning electron microscopy (SEM), X- ray fluorescence spectroscopy (XRF), X - ray diffraction (XRD), high performance ion chromatography (HPIC) and other instruments were used to analyze the corrosion products of the bronze sword and the soil around its burial site. The results show that the bronze sward is severely corroded. Copper has been lost and the major corrosion products are Sn compounds. By measuring corrosion potential and determining the potential - pH of the Cu - Hz 0 system the progress of corrosion of this bronze can be deduced. These results will provide useful information for similar relics.
