    Notes: A group of 115 patients with orofacial complaints has been examined. A new method for intraoral measurement of electrode potentials on the surface of the amalgam fillings and prosthetic constructions has been developed and applied. The possible connections between the measured electrode potentials and patients' saliva properties and their complaints have been discussed. No correlations between measured electrode potentials of the metallic fillings and constructions and important saliva properties could be found. No connections between the measured electrode potentials and the patients' complaints could be proved.

    Notes: Electrochemical measurements on amalgams and gold alloys in natural saliva and saline solutions have been performed.The results show strong inhibiting effects of some components in natural saliva on the surface corrosion behaviour of amalgams.For the gold alloys the cathodic reduction of oxygen was notably lower in natural saliva than in saline solutions.For galvanic combinations of gold and amalgams substantially lower currents than those calculated from thermodynamic data can be expected in natural saliva.

    Description / Table of Contents: Einfluß von Kohlepartikeln auf die Korrosion von Eisen in einer feuchten, schwefeldioxidhaltigen AtmosphäreEisenproben, bedeckt mit einer dünnen Schicht Aktivkohle, wurden bei verschiedenen Werten der relativen Feuchtigkeit Atmosphären mit verschiedenem Schwefeldioxidgehalt ausgesetzt. Im Gegensatz zu den Erwartungen war die Anfangskorrosion bei 55 und 65% relativer Feuchtigkeit stärker als bei höheren Feuchtigkeitswerten. Diese Erscheinung wird der Adsorption von Wasserdampf an der Aktivkohle zugeschrieben, da hierdurch der die Korrosion auslösende Flüssigkeitsfilm schon in einem frühen Stadium entstehen kann. Nach längerer Versuchsdauer hingegen kann keine beschleunigende Wirkung der Kohleteilchen mehr festgestellt werden.
    Notes: Iron samples covered with a thin layer of activated carbon have been exposed to humid atmospheres at various relative humidities and with a various sulfur dioxide contents. Contrary to expectation the corrosion is initially faster at 55 and 65% relative humidity that at higher humidities. This phenomenon is attributed to adsorption of water vapour on activated charcoal, so that liquid films giving rise to corrosion can be formed at an earlier stage. After extended exposure, however, no accelerating effect can be attributed to the carbon particles.

    Description / Table of Contents: Korrosionsinhibierende Eigenschaften von Bleimennige - I. Pigmentsuspensionen in wässerigen LösungenMit Hilfe von potentiostatischen Untersuchungen wird gezeigt, daß eine wässerige Aufschlämmung von Bleimennige in 0,1 m Natriumperchloratlösung sowohl das anodische als auch das kathodische Verhalten von Stahl beeinflußt. Die Sauerstoffreduktion an der Kathode inhibitorfreien Lösung verlangsamt. Aufgrund von Untersuchungen mit dem Rasterelektronenmikroskop und der Mikrosonde sowie der Röntgenbeugungsanalyse nach Guinier besteht die bei etwa -1100 mV an der Kathode entstandene Schicht aus metallischem Blei, Bei negativeren Potentialen entsteht eine bisher noch nicht identifizierte Phase.
    Notes: It has been shown by means of a potentiostatic technique that both the anodic and the cathodic behaviour of steel are inhibited in an aqueous red lead slurry with 0.1 M sodium perchlorate as supporting electrolyte. The oxygen reduction on the cathode takes place at a slower rate in the slurry than in the pure electrolyte solution. According to scanning electron microscopy with microprobe analysis and Guinier X-ray diffraction phase analysis, the layer formed on the cathode at about -1100 mV consisted of metallic lead deposited from solute lead species. At more negative potentials and unidentified phase appeared.

    Description / Table of Contents: Atmosphärische Korrosion von ungeschütztem Kohlenstoffstahl: Vergleich zwischen Feld- und LaboratoriumsuntersuchungenDie Ergebnisse von Freibewitterung und beschleunigter Bewitterung von ungeschütztem Kohlenstoffstahl werden miteinander verglichen. Bei der Freibewitterung wird die Korrosionsgeschwindigkeit als Funktion einiger Klimafaktoren (z. B. S02-Konzentration) ausgedrückt. Bei den Laborversuchen bestand die Prüfatmosphäre aus Luft mit bekannten Mengen Schwefeldioxid und Feuchtigkeit; dabei wurden die Versuche so durchgeführt, daß sowohl die SO2-Zufuhr als auch die SO2-Bindung an der Oberfläche bekannt waren. Zwischen der empirischen Formel und den Ergebnissen der Laboratoriumsversuche ergibt sich für SO2-Mengen unter etwa 0,5 μg · h-1 · cm-2 gute Übereinstimmung.
    Notes: A comparison is made between the atmospheric corrosion of unprotected carbon steel in outdoor exposures and results from laboratory tests. The atmospheric corrosion in the outdoor exposures is expressed as a function of certain atmospheric parameters (e.g. SO2 concentration). In the laboratory tests the atmosphere consisted of air containing known amounts of SO2 and water vapour. The experiments were carried out in such a way that both supply and deposition of SO2 was known. There was good agreement between the empirical formula and the results from the laboratory tests provided that the supply of SO2 in the laboratory test was below ca. 0.5 μg · h-1 · CM-2.
