“…This difference in the corrosion resistance of iron and nickel is at least partially retained in their solid solution: according to the XPES analyses, the interaction with the solution makes the alloy surface become enriched in nickel. The same data taken together with the x-ray structural microanalysis (carried out in this work and in [13]) confirm also the heightened resistance of phosphorus, which, similarly to nickel, is accumulated at the surface during the dissolution of iron.…”

With the use of tracers, the separate effect of small nickel additions, as well as phosphorus and manganese impurities (including their combinations with sulfur) on the corrosion electrochemical behavior of active iron is studied. Nickel (2.2%) and phosphorus (only 0.07%), which are substantially more corrosion resistant than iron, are found to noticeably suppress the active dissolution of iron from its alloys, whereas the unstable manganese (0.43%) and its sulfides (in an alloy containing 0.43% Mn and 0.06% S) accelerate the dissolution. An effect similar to that of manganese is produced by a simple increase in the defectiveness of the iron crystalline structure. The largest deceleration is observed at a small surface coverage of the dissolving alloy with nickel or phosphorus, whereas the activating effect of manganese and its sulfides is accompanied by their selective transfer to the solution. With an increase in the potential, both effects decrease in magnitude. Generalizing these and other data on the effects of impurities and structural defects on the active dissolution of iron made us reveal the substantial effect of the metal purity and its surface defectiveness (including that induced by a potential increase) on the steady-state kinetics of the process. All the regularities of the effect theoretically follow from the crystal-chemistry concept of dissolution.

rer. nat. Hans-Jurgen Engell zurn 60. Geburtstag gewidmet E. Riecke, 6. Johnen und H. J. Grabke' Die Einflusse der in Stahlen ublichen Begleit-und Legierungselemente C, S , P, Mn, Si, Cr, Ni, Sn und Cu auf die Aufnahme und Permeation von Wasserstoff durch Eisen wurden mit Hilfe der elektrochemischen Permeationsmethode an binaren Eisenlegierungen untersucht. Zur Beschreibung des Einflusses der Legierungszusatze auf die Wasserstoffaktivitat an der Metalloberflache sowie den Wasserstofftransport im Volumen wurden der Permeationskoeffizient, der Diffusionskoeffizient und die Loslichkeit des Wasserstoffs fur Temperaturen zwischen 10 und 80°C bestimmt. Die stationare Wasserstoffpermeation wird allein durch Si und Cr starker gehemmt. Si erniedrigt vor allem die Loslichkeit des Wasserstoffs in Eisen und hemmt weniger die Diffusion. Cr verursacht im Eisengitter Platze hoher Bindungsenergie (-58 kJ/mol) fiir Wasserstoff und erniedrigt damit dessen Beweglichkeit . Die Gesamtwasserstoffkonzentration wird durch Cr erhoht. Permeationsmessungen an handelsublichen Stahlen zeigen vor allem den Si-Einflul3.
