Outline of Final Research Achievements

The target of the present study is to construct a safe and efficient management system for iron artifacts, which is based on the prediction of deterioration characteristics. The experimental methods that simulate the corrosion of iron artifacts in archaeological sites were conducted for an understanding of the corrosion mechanism of iron artifacts. The result revealed the effect of the soil moisture and dissolved oxygen on the corrosion behavior of them in the site.

Academic Significance and Societal Importance of the Research Achievements

国内外の埋蔵文化財を収蔵する施設では発掘によって年々増加するすべての鉄製文化財を空調で環境制御した収蔵庫で保管することは設備、運用費用の点で現実的に困難な状況にある。本研究で得られた成果から発掘後の考古資料の劣化特性に応じた保管管理を選択することが可能になり、鉄製文化財のより安全な保存が実施できるとともに、保存管理にかかわる費用が大幅に軽減され得ると期待される。
