摘要
运用 SEM,XPS,EPMA,Micro-XRD,IR 及 AAS 等仪器分析手段对两块绿漆古铜镜进行了结构成分分析。结果表明,在铜镜表面层中,Sn、Si 的元素含量远高于合金基体内部;表面层下的过渡层内有 O、C、Cl、P 等生锈元素,并有明显被腐蚀痕迹。文章对表面层下的生锈途径进行了探讨;对绿漆古铜镜的特殊成因进行了探索。古铜镜表面加工过程进行的推测,对青铜文物保护有一定参考价值。
The composition and structure of two pieces special ancient bronze“green mirror”were detected by methods of SEM,XPS,EPMA,Micro-XRD,IR and AAS.It was found that,in the surface lay- er of the mirrors there were much more elements of Sn and Si than in the original alloy matrix;in the transition layer,which was between the surface layer and the matrix,some corroding elements P,O, C,CI were found and the alloy is corroded clearly.The corroded path under the surface layer is searched;the special reason of the ancient bronze green mirror is discusse.In the present work,the ancient treating process on the surface of the bronze mirror.The present research has some reference value for the protection of the cultural bronze relix.
