| The stability of metal parts in electrolytic environment is a function of external and internal cell field bias. Therefore, in order to achieve long-term integrity of electrolyser cell components, the alloys and plated metals used should be evaluated with respect to stray current corrosion. For this purpose, three different materials were tested in this study in specially designed electrochemical cells. The materials were carbon steel, Ni-electroplated carbon steel, and electroless Ni plated on carbon steel.; In this comparative study, the corrosion of the three materials was investigated using both thermodynamic predictions (Pourbaix diagrams) and potentiostatic and weight loss data obtained from immersion testing for the three materials. Effects of turbulence, hydrogen gas, and temperature variation on corrosion were also examined for the above materials.; Finally, electroplated Ni and electroless Ni plated carbon steel showed excellent resistance to stray current corrosion under the specific electrolyser conditions. |
