摘要
The Chinese ancient bronze black mirror'Hei-Qi-Gu'is famous for its black colour,bright surface and anti-corroding property.In the present work,methods of SEM,IR,EPMA,Memhrane-XRD, and AFM were employed to detect the composition and structure of several pieces of Hei-Qi-Gu fragments.It was found that after casting,the surface of the bronze mirror was treated by a special process,and most of Cu was moved away while Sn and Si were rich in the surface layer.The oxides SnO_2 and SiO_2 on the surface in a very small particle size are particularly stable and they protect the bronze alloy successfully. The surface layer and the transition layer have been dissected mainly,and some important informa- tion has been obtained.The special treating process of the mirror surface is searched and discussed.
