摘要

The need for in situ preservation of archeological artifacts has grown owing to environmental concerns, particularly in Japanese tumuli. This study evaluated corrosion factors within stone chambers using Fe-Ag atmospheric corrosion sensors and environmental investigations of a simulated tumulus. The results showed that the total wetness area and time were critical for corrosion, whereas temperature and oxygen concentration showed no clear correlation. Seasonal variations affected the corrosion mechanisms: summer corrosion was accelerated by persistent water films from direct condensation and rainfall-derived ceiling drips, whereas winter corrosion proceeded slowly owing to intermittent water films from ceiling drips. These films formed via dew formation because of temperature gradients, as the relative humidity remained at 100%. In burial soil, increased moisture expanded the wetted surface area and promoted corrosion; rainfall infiltration enhanced this effect. Two strategies are proposed: enhancing mound thermal insulation to reduce temperature gradients and condensation, and modifying the mound structure to limit rainwater infiltration.
