Abstract: In the process of long-term burial and preservation, ancient bronzes suffer from various kinds of corrosion, among which “powdery rust” causes serious damage to bronzes. Focusing on the factors such as alloy composition, casting technology and occurrence environment of ancient bronzes, the causes of “powdery rust” of ancient bronzes were summarized, the types of “powdery rust” were introduced, the main influencing factors of the occurrence and development of “powdery rust” were analyzed, and the key research directions of “powdery rust” disease of bronzes were prospected.
