| 摘 要： | “黑漆古”铜镜的表面由非金属层和过渡层组成,价电子结构分析指出,非金属层主要成分Sn1-xCuxO2具有与SnO2相近的稳定性,而实验数据分析发现,过渡层中,δ相铜锡合金与Sn1-xCuxO2的相界上存在着重合位置点阵(CSL)结构,这种结构降低了相界面上铜原子的能量,使这部分δ相晶粒也十分稳定,从而使整个“黑漆古”表面具有耐腐蚀性能。

| Abstract: | The surface layer of the bronze mirror "Hei Qi Gu" is composed of non-metal layer and transition layer. The valent electron structure analysis points out that the main phase of tran-sition Sn1-xCuxO2 is similar to SnO2 in stablility. It was found from study of experimental data that there is the coincidence site lattice structure at the phase boundary between the δ-phase Cu-Sn alloy and Sn1-xCuxO2 in the transition layer. This structure reduces the energy of Cu atoms at the phase boundary and makes the δ-phase Cu-Sn alloy stable, which is the main reason for corrosion resistant of the "Hei Qi Gu". |
