USS Arizona Preservation Project- Corrosion

Summary

This is an abstract from the session entitled "Hard Science on Hard Steel: Scientific Studies of the USS Arizona" , at the 2020 annual meeting of the Society for Historical Archaeology.

During a visit to the USS Arizona Memorial in 1998, samples from Wapio Point, Pearl Harbor were provided the author and delivered to the UNL Department of Mechanical and Materials Engineering for metallurgical examination. Subsequent field operations in 2002 focused on potential/ pH measurements and acquisition of hull core samples. Surveys and concretion analysis lead to the development of the Concretion Equivalent Corrosion Rate (CECR). CECR, a non destructive method to estimate corrosion rate , has been applied to shipwrecks from the North Atlantic, Bay of Panama, East and West coast of US and Canada and offshore Ohau, HI. Correlating CECR with environmental parameters, the dimensionless Weins Number was developed to relate wreck sites, one to another, as a function of reciprocal absolute temperature. The “Secant Rate of Corrosion” model, based on attack (1941) evidence embedded in concretion, is proposed to account for non-linear high early stage corrosion.
