In this paper, digital video microscopy, scanning electron microscopy with energy dispersive Xray, Raman spectroscopy, and XRay Fluorescence were used to study the microcorrosion morphology,alloy composition,metallurgical structure and phase and elemental composition of a Han Dynasty thin bronze mirror excavated from the Liushugou Cemetery in Hubei Province. The degree of corrosion,material,metallurgical structure and type of surface corrosion were determined. Based on the results,it is tried to restore the original look of the object by cleaning, spot welding, bonding, completing the missing part, balancing the color and coating with protective materials.
