... corrosion in acidic solutions leads to hydrogen generation via the cathodic reaction. Additionally, the pH at the crack tip during stress-corrosion cracking is known to have a lower pH due to the hydrolysis of the ferrous ion.[ 1 ] Based on the intergranular attack seen on the interior surface...

... at temperatures in excess of 100 °C (212 °F). Some acidification of the solution trapped in the crevice between the wear rings is possible under static conditions because of hydrolysis effects and the buildup of impurity species in the crevice. Loss of passivation by the nickel would leave it more susceptible...

... solutions, the pH value of the solution at the crack tip was measured to be approximately 3.5, regardless of that of the bulk solution. At the crack tip, where diffusion is limited, the pH value of the solution is lowered by the acidic hydrolysis reaction, and in such a low-pH solution, the cathodic partial...
