    Notes: Abstract The paper deals with the principles of cathodic protection for atmospherically exposed concrete structures, the various protecting effects induced by the cathodic polarization and tests and field experience results. The differences between the cathodic protection applied for controlling the corrosion rate of chloride contaminated co nstructions and that applied to improve the corrosion resistance of the reinforcement of new structures expected to become contaminated are then underlined and discussed. The more recent applications of cathodic protection on carbonated concrete are also illustrated. The operating conditions (voltage and current applied), the throwing power, the protection conditions which avoid the risk of hydrogen embrittlement in prestressed structures are also discussed. Examples of cathodic protection and of cathodic prevention are also presented.

    Description / Table of Contents: Beitrag zur Kenntnis der Beziehungen zwk schen dem elektrochemischen und dem Korrosionsverhalten sowie dem Gefüge von metallischen Werkstoffen nach plastischer VerformungIm Rahmen einer systematischen Untersuchung über die Wirkung einer plastischen Kaltverformung auf das elektrochemische (anodische und kathodische) Verhalten und das Korrosionsverhalten (Korrosionsgeschwindigkeit im Aktivbereich, ermittelt nach Sterm und Geary durch Bestimmen des Gewichtsverlustes) von metallischen Werkstoffen werden die Ergebnisse mitgeteilt, die mit den nichtrostenden austenitischen Stählen AISI 304, 304 L und 316, Armco-eisen und wurden durch Zugbeanspruchung verformt und dann in entlüfteter Schwefelsäure geprüft. Die Ergebnisse werden erörtert, mit dem Ziel, das Verhalten der Werstoffe in Abhängigkeit von ihrer Struktur darzustellen.
    Notes: Within the framework of a systematic study of the effect of cold plastic deformation on the electrochemical behaviour (anodic and cathodic characteristics) and the corrosion behaviour (corrosion rates in the active region, evaluated by the method of Stem and Geary and by loss in weight) of metallic materials, the results relating to the case of austenitic stainless steels AISI 304, 304 L and 316, ARMCO iron and nickel deformed by tension and immersed in de-aerated sulphuric acid solution are presented and discussed with the aim of interpreting these aspects of their behaviour on the basis of the “structure” of the deformed materials.
