Abstract
This paper describes the corrosion behavior of a Ti-based alloy, Ti-Al-Zr for aggressive nitric acid applications. Corrosion behavior of the materials was established using electrochemical polarization technique, for three process variables encountered in reprocessing plants: (a) nitric acid (1, 3 and 6 M), (b) temperature (25 and 75 °C) and (c) oxidizing ions (Ce+4 and V+5 ions). Electrochemical polarization tests established that the Ti-Al-Zr alloy was in passive condition up to a potential of 4000 mVAg/AgCl even at 75 °C, and it showed uniform corrosion. SS304L, however, showed severe intergranular corrosion at a much lower anodic potential, thus establishing better corrosion resistance for Ti-Al-Zr alloy in the aggressive nitric acid environment.
