Abstract
Results are summarized of the feasibility of using electrochemical methods for the evaluation of the mass transfer resistance of corrosion‐resistant austenitic steels in liquid sodium.
First a brief note is presented about the historical background of the concept of the electrochemical evaluation of the carbon content in austenitic steels, and results are described of investigations into the effect of carbon on voltametric curves in austenitic steels in a buffer solution of pH = 4. Then results are presented of the measurement of voltametric curves for austenitic steels exposed to liquid sodium, showing the influence of the etching time or of the distance from the surface, and an electrochemical method is proposed for the determination of the carbon concentration profile in a surface layer on corrosion‐resistant austenitic steels.
