The effect of shock deformation on the anodic polarization behavior of polycrystalline nickel in 1N sulphuric acid

The results of anodic potentiostatic polarization of shocked nickel polycrystals in 1N H₂SO₄ are reported. With increasing shock pressure, passivation and Flade potentials shift in the cathodic direction, the critical current density decreases, and the passive current density decreases. These effects are discussed in terms of substructural changes accompanying shock loading.
