The cathodic branch was performed -1000 mV from the rest potential and the anodic branch went up to 2000 mV from that same rest potential.
It is generally referred to as a steel native potential or a free corrosion potential, although it can also be an instant off-potential, a decayed off-potential, or a rest potential. The values of these potentials can be measured correctly only when there is absence of interference by stray currents or long-line currents.
Nevertheless, if the steel native or rest potentials can be known, the level of cathodic polarization applied on the steel pipe surface for a given off-potential can be evaluated and provides a more direct measure (than an off-potential) on the magnitude of corrosion rate reduction.
The meanings of on- and off-potentials, polarization (decay or growth) and ohmic voltage drop (IR), native and rest potentials are labeled and shown clearly.
Figure 4 shows the native or rest potentials of operating pipelines or installed coupons vs.
The open circuit potential (also referred to as the equilibrium potential, the rest potential, or the corrosion potential) is the potential at which there is no current.
The change of [pH.sub.i] from 7.2 to 8.5 produced a slight hyperpolarization of rest potential by about 1 mV.
We are proposing that the reduction of [I.sub.L] with increasing [pH.sub.i] allows the negative slope character of [I.sub.NaP] to destabilize the equilibrium point (rest potential) of the axon at --60 mV, thereby resulting in autonomous activity.
The ionic model that we propose for the spontaneous activity is novel and counterintuitive, in that the effect is attributable to a reduction of inward current, thereby leading to a destabilization of the rest potential by the [I.sub.NaP] component.
