“…Above this maximum pitting potential, pit formation is completely eliminated, which may be attributable to inactivation of the vacancies by the high chloride concentration in the medium and the high molybdenum concentration in the material itself [7][8][9]. This upper limit of the pitting corrosion range should not be confused with the pitting inhibition potential described in ref.…”

“…Es sei erwähnt, dass in wenigen Fällen an hoch mit Mo legierten Werkstoffen in hoch chloridhaltigen Medien ein Begrenzungspotential der Lochkorrosion U L,Begrenzung beobachtet wird, oberhalb dessen keine Bildung stabiler Löcher erfolgt [5].…”

“…Während im NaCl-Test die Unterschiede zu den im FeCl 3 -Test ermittelten kritischen Lochkorrosionstemperaturen gering und nicht systematisch sind [36], können mit dem CaCl 2 -Test auch die höchstlegierten NiCrMo-Legierungen getestet werden [5,37]. Das niedrige Prüfpotential von 0,2 V (GKE) im CaCl 2 -Test im Vergleich zu den hohen Redox-bzw.…”

“…The applicability of electrochemical test methods for the examination of the pitting corrosion behavior of NiCrMo alloys is restricted due to the limitation of the potential range where pitting corrosion occurs in anodic direction. Werner et al 5 showed that for alloys with more than 6.5 mass% molybdenum in solutions which contain more than 2 M chloride polarization up to the passive range is possible without initiation of pitting corrosion, due to repassivation effects. Based on these observations, a potentiostatic test in a 4.5 M calcium chloride solution was developed by IKS Dresden 4.…”
