“…The formation of a pure ionic bond has also been reported. Koutecky et ~· (12,13) have discussed the electronic structure of diamond and attempted to relate the existence of surface states to the normal bonds of the crystal lattice. They concluded that the (100) surface is characterized by lone electron pairs which tend to form donoracceptor bonds with gas molecules.…”

Nach einer Ubersicht uber die Vielzahl der sowohl vom Metall als auch vom angreifenden Medium abhangenden Faktoren, welche die anodische Metallauflosug beeinflussen konnen, wird die Natur der Passiv-Schichten auf Grund elektrochemischer und optischer Untersuchungen behandelt. Die fur die Passivierung charakteristische steile Abnahme der anodischen Stromdichte bei wachsender Galvanispannung wird schon durch eine monomolekulare, den Durchtritt der Metallionen durch die Phasengrenze hemmenden Schicht hervorgerufen. Das Wachstum dieser Schicht wird majgeblich durch Transportvorgange vor allem in ihr selbst beeinfkrjt. Die Kinetik der Passivierungs-und Aktivierungsvorgange la& sich durch p~tentialabhang~ge, Jconkurrierende S~mu~tanreaJ~fionen deuten, wobei die Austawchadsorption im Passiv-Verhalten eines Metalls gegeniiber verschiedenen Sauren eine Rolle zu spielen scheint.

After a survey of the various factors, depending both on the metal and on the attacking substance, that can influence the anodic dissolution of metals, the nature of the passive layer is discussed on the basis of electrochemical and optical studies. Passivation is characterized by a rapid decrease in the anodic current density as the Galvani tension is increased; this is due to the presence of a monomolecular layer, which prevents the metal ions from passing across the phase boundary. The growth of this layer is strongly influenced by transport processes, particularly within the layer itseIf. The kinetics of the passivation and activation processes can be explained by the simultaneous occurrence of competing reactions which depend on the potential; exchange adsorption appears to play some part in the passive behavior of metals towards various acids.
