| Abstract |
The additional methods were being investigated for use in determining concretion equivalent corrosion rates (CECR) of steel shipwrecks in the marine environment with a minimal impact on the existing structure are discussed. Concretion samples have been microscopy, and corrosion potential (E corr) to characterize the relationship between concretion and the steel substrate. X-ray and electron diffraction data confirm the viability of the CECR to determine the corrosion rate. The CECR is based on analyzing concretion from USS Arizona. Further analysis is required at other sites to confirm the correction factor of 1.6, where testing is ongoing and further refinements may be necessary. Concretion analysis appears to be a viable proxy for the direct sampling of hull metal to minimize impact on the ship's existing structure. |
