Die folgende Tabelle zeigt die Ergebnisse von Versuchen, welche die Wirksamkeit der erfindungsgemässen Mittel bei der Hemmung metallischer Korrosion beweisen. Diese Versuche wurden in synthetischem Pittsburgh-Wasser durchgeführt. Stahlelektroden wurden in Polarisationstestzellen verwendet, wobei der pH-Wert anfangs bei 7»0 lag. Die Inhibitorkonzentrationen wurden auf der Basis von 100 % aktivem Material berechnet. Der Grad der eingetretenen Korrosion wurde aus der Stromdichte am Schnittpunkt einer extrapolierten Kurve des sogenannten "Tafel"—Teils der Anodenpolarisationskurve mit dem Gleichgewichts- oder "gemischten" Potentialwert bestimmt (üblicherweise als Korrosionspotential, "E " bezeichnet). Die Anwendung des Faraday1sehen Gesetzes gestattet, eine direkte mathematische Beziehung zwischen der Stromdichte bei E ,The following table shows the results of tests which prove the effectiveness of the agents according to the invention in inhibiting metallic corrosion. These tests were carried out in synthetic Pittsburgh water. Steel electrodes were used in polarization test cells, the pH initially being 7 »0. The inhibitor concentrations were calculated on the basis of 100% active material. The degree of corrosion that occurred was determined from the current density at the intersection of an extrapolated curve of the so-called "Tafel" portion of the anode polarization curve with the equilibrium or "mixed" potential value (commonly referred to as the corrosion potential, "E"). The application of Faraday 1 see law allows a direct mathematical relationship between the current density at E,
