Title
Study on Corrosion Factors of Iron Artifacts Recovered from the Middle West Sea
Description
This study investigates corrosion process through analysis of corrosion products and desalination solution as a
precedent study to present proper conservation treatment methods for iron artifacts collected from the middle
West Sea. Depending on the environment where the iron artifacts were buried underwater, the corrosion patterns
may be different. In order to treat the heritage stably and effectively for conservation, the major corrosion factors
and information to remove or control the factors should be obtained. The underwater environment is rich in
water, oxygen and salt, and it is very easy for iron artifacts to be corroded. In an environment where oxygen
supply is little like seabed mud, anaerobic corrosion may occur. The iron artifacts in the seabed may be deeply
buried in the mud or exposed on the surface of the seabed. This study intends to obtain information on the
corrosion pattern of iron artifacts collected from the seabed surface of middle West Sea. In addition to those
deeply buried in dense silt, there are also cases of recovering those exposed on the seabed or shallowly buried in
the surface layer. In this study, we obtained information on the corrosion patterns of iron artifacts recovered from
the seabed layer in the central West Sea.The samples used in the study were corrosion products from iron
artifacts excavated from waters of Mado, Taean and of Seomeopbeol, Ongjin and desalination solution and the
major components of corrosion products and anions of desalination solution were analyzed using Scanning
Electron Microscope-Energy Dispersive Spectroscope (SEM-EDS) and X-ray Diffraction (XRD), Ion
Chromatography (IC). The analysis result shows that major components including P, S and Mackiwanite (FeS)
were identified as compounds related to it. In the desalination solution, high concentration of Cl
- and SO4
2- was
measured. It is expected that this study result can be utilized as essential data for establishing methods for
effective and systematic conservation of iron artifacts excavated from underwater and it is intended to continue
additional studies such as analysis on corrosion product of iron artifacts recovered from various waters and
corrosion reproduction experiment through collaboration with various fields.
