The active dissolution of cobalt leads to an initial CoO film formation.
Two anodic peaks were found in the active dissolution region of the anodic voltammogram.
At higher halide concentrations the prepassive film is removed and active dissolution occurs.
Two anodic peaks were found in the active dissolution region of the voltammogram.
Passivation of chromium was found to take place without relation to active dissolution.
The active dissolution occurs via transport of ions through a spontaneously formed iron oxide (hydroxide) film.
Therefore, active dissolution behaviour is mainly dominated by the alloying element Co.
AddiThen of SO42− ions decreases the rate of potentiodynamicowth anodice incubation time, while the reverse changes polarizationaddition of either WO42− or MoO42− ions.
The potentiodynamic polarization study shows that both the coatings have similar active dissolution behaviour.
The synergistic effect of stress field and dissolved hydrogen on active dissolution (corrosion) is negligible.
Rotating-disc and impedance studies of the active dissolution of tin in NaOH solutions are reported.
