Determining the condition diagram of the metal/electrolyte systemIn this paper, the corrosion reaction is examined on the strength of theoretical results which are experimentally accessible. The corrosion rate was represented by the differential equaiton \documentclass{article}\pagestyle{empty}\begin{document}$$ dv = \left( {\frac{{I \cdot v}}{{I \cdot c}}} \right)_{t,T} + \left( {\frac{{I \cdot v}}{{I \cdot t}}} \right)_{c,T} dt $$\end{document} where t is the duration of the test, c the concentration of the corrosive substance, and T the temperature. This equation has two characteristic terms: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{c} \left( {\frac{{Iv}}{{Ic}}} \right)and\left( {\frac{{Iv}}{{It}}} \right).\,\,{\rm The\,\,equation} \\ v = Kc^n t^n\,e^{ - kct} \end{array} $$\end{document} can be used for the linear, hyperbolic and exponential corrosion rate v = f(c) or v = f1(t).
Notes:
In diesen Beitrag wird die Korrosionsreaktion auf Grund theoretischer und experimentell zugänglicher Ergebnisse verfolgt. Die Korrosionsgeschwindigkeit v wurde durch die Differentialgleichung \documentclass{article}\pagestyle{empty}\begin{document}$$ dv = \left( {\frac{{I \cdot v}}{{I \cdot c}}} \right)_{t,T} + \left( {\frac{{I \cdot v}}{{I \cdot t}}} \right)_{c,T} dt $$\end{document} dargestellt, wobei t die Versuchsdauer, c die Konzentration des aggressiven Stoffes und T die Temperatur bedeuten. Diese Gleichung besitzt zwei charakteristische \documentclass{article}\pagestyle{empty}\begin{document}$$\begin{array}{c} Glieder{\rm }\left( {\frac{{Iv}}{{Ic}}} \right)und\left( {\frac{{Iv}}{{It}}} \right).\,{\rm Die\,\,Gleichung} \\ v = Kc^n t^n\,e^{ - kct} \\ \end{array}$$\end{document} Kann man für die lineare, hyperbolische und exponentielle Korrosionsreaktion v = f (c) bzw. v = f1(t) verwenden.
