Cathodic protection of stainless steel in boiling nitric acid solutions

Uchiyama, Yohei; Kato, Chiaki ; Ueno, Fumiyoshi ; Yamamoto, Masahiro

The cathodic protection applications of reprocessing plant made of stainless steel in boiling nitric acid solutions was studied. In this study, 304ULC stainless steels in 3N HNO $_{3}$ solutions was investigated, Saturated Silver chloride Electrode (SSE) was used as reference electrode. Results of potentiostatic corrosion test was that corrosion rates shows an exponential function increase with rises of potential in transpassive state regions and finded possibility of the cathodic protection applications. Corrosion rates with cathodic protection was about one fortieth of without cathodic protection in boiling nitric acid solutions added 10 g/L vanadium ions (imitation solutions of reprocessing).
