Wagner theory, generalized

Theories of oxidation have been developed by Wagner and by Mott ° . In general the logarithmic rate law applies to very thin oxide layers which form protective coatings and the parabolic rate law to thick oxide layers. More recent reviews of the subject have been given by Grimley , Kubaschewski and Hopkins and by Wyn Roberts . ...

Solid materials, in general, are more or less subject to corrosion in the environments where they stand, and materials corrosion is one of the most troublesome problems we have been frequently confronted with in the current industrialized world. In the past decades, corrosion science has steadily contributed to the understanding of materials corrosion and its prevention. Modem corrosion science of materials is rooted in the local cell model of metallic corrosion proposed by Evans [1] and in the mixed electrode potential concept of metallic corrosion proved by Wagner and Traud [2]. These two magnificent achievements have combined into what we call the electrochemical theory of metallic corrosion. It describes metallic corrosion as a coupled reaction of anodic metal dissolution and cathodic oxidant reduction. The electrochemical theory of corrosion can be applied not only to metals but also to other solid materials. 

General aspects of the theory and of its application to experiments have been elaborated in a number of recent books or monograph articles. Among them are the work of Robinson and Holbrook, Forst, Nikitin, Troe, - Rice, SetsCT, Troe and Wagner, " and Spicer and Rabinovitch. The close connection of... 

The reader may note that there is now a tendency to use some of the results consistent with scaling theory and the data in conjunction with an assumed analytic ES. Examples are (1) a non-analytlc vapor pressure equation such as that of Goodwin or of Wagner and (2) m = 3,4 in constraint 5, above. While theoretically inconsistent, an analytic ES so constrained generally provides a... 

The empirical phase of the development of solid electrolyte fuel cells was overcome only after many general advances in research on solids. These included development of X-ray structure analysis, new knowledge on the ion conduction of solids from the measurements of transport numbers by Tubandt (first detection of unipolar conduction by anions), the establishment of the theory of disorder in solids by Frenkel, Schottky, Wagner and Jost, and the development of isotope methods for the investigation of diffusion processes in solids.
