ON THE ELECTRON-CONFIGURATION THEORY OF MARINE CORROSION

The electron-configuration theory of corrosion introduced by Uhlig relates chemisorption and passivity to alloy compositions having favorable d-electron configurations. Recently, detailed knowledge of the electronic structure of Cu-Ni alloys has been greatly increased, and it no longer appears that a strict band model alone can give an adequate description of the disordered alloys. This paper investigates whether or not there is any evidence to support an electron-configuration theory of corrosion, without regard to the question of passivity, for Cu-Ni alloys in saltwater. The addition of small amounts of Fe has important effects on the corrosion rate in the copper-rich alloys and the relevance of this to the electron-configuration theory is considered. Effects of metallurgical variables and of film properties are noted. The related topic of heterogeneous catalysis is discussed.
