Abstract
The data supplied by electrochemical methods such as potentiodynamic polarization curves and potentiostatic anodic transients show that in methanolic solution a region of unstable passivity for Armco iron and Ni-Cr-Mo low alloy steels results from the overlapping of certain ranges of solution composition (e.g. acidity up to 10-3 M as sulphuric acid, chlorides 10-4 to 10-3 M, water 0.01-0.5%). Slow strain rate tests indicated that the instability of the protective oxide films can induce susceptibility to stress corrosion cracking in the presence of applied stresses. © 1988.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
