【摘要】：目的对山西博物院馆藏大量珍贵青铜器的锈蚀情况进行分析,为后续的保护修复提供科学依据和数据支持。方法选用21件山西省出土的馆藏青铜器,通过超景深显微镜、偏光显微镜、拉曼光谱分析等手段,对青铜器物表面锈蚀物进行综合分析,确定有害锈蚀物。结果这批青铜器表面锈层结构有5类,绿色锈蚀物主要为孔雀石、氯铜矿,其中氯铜矿为青铜器有害锈蚀的主要成分,少量绿色锈蚀物为斜氯铜矿、水胆矾,红色锈蚀物为赤铜矿,蓝色锈蚀物为蓝铜矿。结论青铜器表面的孔雀石锈蚀物大多结构致密,对青铜器本体无害,还可阻隔铜与空气、水分等物质的直接接触,对器物具有一定的保护作用,可以保留。氯铜矿对青铜器的保存具有隐患,在修复中应对其彻底清除。

[Abstract]:Objective to analyze the corrosion of a large number of precious bronzes in Shanxi Museum, and to provide scientific basis and data support for subsequent protection and repair. Methods 21 pieces of bronze ware unearthed in Shanxi Province were selected. The surface corrosion of bronze ware was comprehensively analyzed by means of overfield depth microscope, polarizing microscope and Raman spectrum analysis, and the harmful rust was determined. Results there were five types of rust layer structure on the surface of these bronzes. The green rust was mainly malachite and chlor copper, in which chlorine copper was the main component of harmful corrosion of bronze, a small amount of green rust was oblique chlorite, water gallbladder alum, red rust was chalcopyrite, and blue copper was blue copper. Conclusion most of the malachite rust corrosion on the surface of bronze ware is compact and harmless to the bronze body. It can also block the direct contact between copper and air, moisture and other substances, and has a certain protective effect and can be retained. Chlorine copper ore has hidden dangers in the preservation of bronze ware, and it should be completely eliminated in the repair.
