Corrosion Evaluation of Army and Automotive Materials in the Hawaiian Islands - 3-Year Update

摘要

The US Army operates in many harsh and demanding environments throughout the world, which are highly corrosive. However, there lacks a basic understanding of the severity of these environments and their impact on the Army's materiel. To better understand this impact and broaden their database of information, the Army has established test sites on the Hawaiian Islands. These sites represent various climatic conditions the Army operates in. In these locations panel exposure of Army and automotive systems have been made to compare performance with that documented in the continental US by the SAE ACAP and past Army programs. Recently the first set of samples exposed has completed three (3) years of exposure. A secondary set has reached its first year of exposure and a third set have completed three (3) months of exposure. This paper will present a summary of the three-year results and future work to be completed.
