INVESTIGATIONS IN THE FIELD OF NONTRADITIONAL ELECTROCHEMISTRY AND CORROSION OF MATERIALS CARRIED OUT BY THE SCHOOL OF FRANTSEVICH,I.N

The electrochemical theory of high-temperature corrosion resistance de veloped by I. N. Frantsevich is briefly reviewed, and a comparative st udy is made of the electrochemical parameters of both the high-tempera ture oxidation of tungsten and its oxidation in I N H2SO4. Considerati on is given to the principal results of experimental and theoretical s tudies of the limiting stages of hydrogen cathodic evolution on the su rface of metals, semiconductors, and certain binary refractory compoun ds. Topics included are the catalytic recombination of hydrogen atoms, their electrochemical desorption, the interaction of hydrogen atoms w ith electrons as disclosed by calorimetric, cyclotron resonance, and E PR methods of investigation. Particular attention is paid to the corro sion of copper and silver coatings on copper parts used in sealed syst ems containing the decomposition products of polymeric insulation. Wea k-current corrosion of contacts, and the electrochemical protection of steel structures in aggressive soils and sea water are also reviewed.
