Multi-element dissolution analysis of amorphous Fe 50 Cr 15 Mo 14 C 15 B 6 in 0.1 M H 2 SO 4 was investigated electrochemically and by coupled online mass spectrometry. We fully discuss the most important aspects of the application of the newly-developed methodology to study complex multi-elemental alloys. The resulting partial dissolution rates of Fe, Cr and Mo reflect the passive behavior and are compared to the measured total current density as function of time. The deviations between the added elemental dissolution currents and the measured total current density are discussed. Furthermore, the inferred growth of oxide thickness was correlated to results obtained from surface analysis.
