Corrosion Characteristics of Bronze Artifacts Excavated from the Songguk-ri site in Buyeo According to Alloy Ratio and Manufacturing Techniques During the Goryeo Dynasty

A comprehensive analysis of the corrosion characteristics excavated bronze artifacts was conducted according to their alloy ratio and microstructure. Corroded by various factors, which resulted in different characteristics. Among these, may occur due difference ratio, is an internal factor. In this study, we tried confirm from Songguk-ri site Buyeo microstructure through a analysis. The differed depending on microstructure, whereas samples subjected tests were same regardless Through this, can be determined based additional effects pH, time burial environment affect metal ion movement, addition future, if similar actual remains long-term test conducted, it will possible mechanism as well artifacts.
