Research Hotspots and Trends in the Corrosion and Protection of Bronze Cultural Relics Based on Bibliometrics

The overall knowledge structure, developmental context, and research frontiers in the field of bronze cultural relic corrosion and protection are lacking. This study employs bibliometric methods to comprehensively analyze 2614 relevant publications from 1906 to 2025 in the Web of Science Core Collection, utilizing the software Citespace 6.2.R3 to construct a knowledge map. The research results based on the number of publications and keyword statistics indicate that the research in this field has undergone a temporal evolution of research trends. Since 2010, the annual number of publications has grown rapidly, peaking in 2024, which reflects the continuously increasing academic attention given to the subject. Globally, China, Italy, and the United States are the leading contributors, forming a closely knit international cooperation network. Among these, China leads in total publications, though there remains room for improvement in its centrality within the collaborative network. Major research institutions are primarily large scientific organizations, such as the National Research Council of Italy and the Chinese Academy of Sciences. Keyword analysis demonstrates that research hotspots have long centered on “corrosion mechanisms and control” and “innovative protection materials and technologies”. Temporal evolution analysis further indicates that the research paradigm is shifting: from the early investigations of mechanisms, through a middle phase focused on material development, to the current emphasis on the development of preventative and intelligent protection systems via multidisciplinary integration. This study systematically reviews the field’s evolutionary trajectory, collaboration networks, and thematic dynamics, providing a comprehensive reference for research planning and future development.
