| 摘 要： | 产于不同环境不同地方的青铜文物经矿相显微镜观察、电子探针成分分析和X射线衍射研究表明，在青铜文物腐蚀层中观察到次生矿物——赤铜矿、孔雀石、蓝铜矿、白铅矿和锡石。由上述矿物组成的腐蚀层在青铜器表面形成保护层。腐蚀层细分为红色赤铜矿层、绿色碳酸盐矿物层和黄色锡石层组成，其厚度小于1mm。青铜合金在潮湿条件下的腐蚀比在干旱条件下要严重，另外青铜合金是适用于作高放废物地质处置系统中的废物罐的候选材质。

| Abstract: | Study of bronze corrosion is applied in nuclear research field. Bronze relics from different locations under different environments were investigated by mineralographic microscope, electronic probe and X-ray diffraction approach. Neogenic minerals of cuprite, malachite, azurite, cerussite and stannolite were observed in corrosion layers of bronze relics. Corrosion layer of bronze relics consisted of red cuprite sub-layer, green carbonate mineral sub-layer and yellow stannolite sub-layer. The corrosion layer together with the neogenic minerals mentioned above can protect the metal from corrosion. Bronze alloy is suitable for selected material of canister in disposal system of high-level radioactive waste. |
