Development of New Materials and Design Configurations to Improve Ceramic Anode Performance.
Abstract
This report documents research to improve performance of the CERANODE, a ceramic anode developed by the U.S. Army Construction Engineering Research Laboratory (USA-CERL) to provide cathodic protection of Civil Works structures. New materials and design configurations for constructing the CERANODE were investigated to find those that would provide the greatest protection from ice and debris impacts, have low material costs, and provide a long service life. Of the plasma-sprayed coatings investigated, the undoped ferrite (Fe3O4) had the longest dissolution rates. Mixed metal oxide coatings such as ruthenium oxide/titanium dioxide and iridium oxide/titanium dioxide have dissolution rates of less than 0.001 g per ampere-year and also show significant advantages as coatings for anodes. The new flat anode configurations developed minimize exposure to damaging ice and debris impacts and are currently being field tested.
