摘要

对清州市五松遗址12点1-1号坑墓出土的青铜剑、青铜剑、青铜镜等进行了金相、SEM-EDS、拉曼显微光谱等分析，研究了制作工艺和腐蚀性能。青铜剑、青铜剑和青铜镜被判定为铜(79.16 ~ 79.89 wt%)-锡(19.12 ~ 20.34 wt%)二元合金。组织为δ相和(α+δ)共析组成的铸态组织，未经热处理。通过对铜匕首、铜剑、铜镜的腐蚀特征进行分类，确定了铜匕首、铜剑、铜镜的腐蚀类型为ⅰ型。在亚表面EDS分析中，氧化锡被定位为(α+δ)共析的选择性腐蚀产物;在拉曼显微光谱分析中，铜匕首和铜剑、铜镜的腐蚀产物分别被鉴定为锡石和孔雀石。次级金属铜主要存在于Pb颗粒腐蚀留下的孔洞和(α+δ)共析上，分析结果表明铜的含量为100.00 wt%，均为高纯铜。

A Study on Manufacturing Technique and Corrosion Characteristics of Bronze Dirk, Bronze Sword, Bronze Mirror in Early Iron Age Excavated from the Osong Site in Cheongju

Metallography, SEM-EDS, and Raman Micro-Spectroscopy analysis were conducted on bronze dirk, bronze sword, and bronze mirror excavated from the pit tomb No. 1-1 at 12th Point of Osong Site in Cheongju to study the manufacturing techniques and corrosion properties. The bronze dirk, bronze sword and bronze mirror are judged to be binary alloys of Cu(79.16∼79.89 wt%)-Sn (19.12∼20.34 wt%). The microstructure is a cast structure composed of δ phase and (α+δ) eutectoid, and no heat treatment was performed. As a result of classifying the corrosion characteristics, it was confirmed that the bronze dirk, bronze sword, bronze mirror were Type I. As a result of EDS analysis in subsurface area, tin oxide is located as a selective corrosion of (α+δ) eutectoid, and as a result of Raman Micro-Spectroscopy analysis, corrosion products of Cassiterite and Malachite were identified for the bronze dirk and Cassiterite for bronze sword and bronze mirror. The secondary metallic copper was mainly present in the hole left by corrosion of Pb particles and on the (α+δ) eutectoid, and was found to be 100.00 wt% of Cu as a result of the analysis, confirming that all of them were high-purity copper.
