Atmospheric Corrosion Behavior of Salvaged Marine Cast iron Artifacts

摘要

The atmospheric corrosion behavior of cast iron after six months immersion was studies by means of optical stereomicroscope and X-ray diffraction techniques. The results showed that active corrosion occurred on the rusted specimen covered with many thin spherical shells of solid material. The XRD analysis indicated the formation of β-FeOOH tends to increase with increasing exposure.
