摘要
为研究汉代铜镜的耐腐蚀性能,采用金相检验、扫描电镜和能谱分析、显微硬度测试以及腐蚀试验等分析手段对三面汉代铜镜残片的结构和成分进行了分析。结果表明:在铜镜表面形成了一层致密的SnO_2氧化膜,能阻止基体铜合金进一步被氧化腐蚀。另外,铜镜的耐腐蚀性能与古代的热处理技术有关。
Metallographic examination, SEM and energy spectrum analysis, microhardness testing and corrosion test were employed to analyze the compositions and structures of three bronze pieces in the Han dynasty to study the corrosion resistance of bronze mirrors in the Han dynasty. The results showed the SnO2 oxidation film on the surface of bronze mirrors could protect copper alloy matrix for further oxidation corrosion. Besides,the corrosion resistance of bronze mirrors was related to the ancient heat treatment technology.
