National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Ionic Current Mapping Techniques and Applications to Aluminum-Copper Corrosion.

DE2004770787

Publication Date	2004
Personal Author	Isaacs, H. S.; Jeffcoate, C. S.; Missert, N. A.; Barbour, J. C.
Page Count	14
Abstract	Measurements have been made of the aluminum metal galvanic couple. A wide range of geometries were investigated varying the areas of anodic and cathodic surfaces and employing speciaIly designed galvanic cells with crevices. In situ ionic current density mapping was used to monitor galvanic corrosion and currents flowing between separated metals was measured.
