The back extrapolation lines intersect at a point on line of corrosion potential, Ecorr, and the projection of this point on the current scale gives the value of the fcorr.
En la Figura 4, se observa como en ambas relaciones a/c el potencial de corrosion (Ecorr) tiende a caer a valores inferiores a -350 mV en el tercer mes.
From this figure, the corrosion potential (Ecorr.) is ascertained and cited in Table 1.
Ecorr RBR regular butyl rubber reclaim products, including Ecorr RBR70 and Ecorr RBR72, are featured in this brochure.
The potentials shown in each of the figures include the native potential (Ecorr), the on- and off-potentials, the "decayed-off" potential (potential measured during depolarization), and the "rest potential" (potential when depolarization becomes steady), or the polarization growth or decay and the IR drop.
It was observed that corrosion potential (Ecorr) moved to noble direction from -212.0mV in RS to -71.82mV when serum concentration was increased to 0.4% in RS as tabulated in table 1.
The surface roughness of laser cut sample was decreased compare to electropolished by the shift of ECorr value of -259 to -173 mV.
