| 英文摘要 | By the artificial pit electrode approach, growth behaviours of stable pits for melt-spun Zr60Ni25Al15 and Zr60Cu25Al15 metallic glasses (MGs) exposed to a 0.6 M NaCl solution are investigated. By characterising the current transient events and growth kinetics parameters, the effect of selective dissolution caused by the late transition metals on the pitting growth kinetics is revealed. The pit solution acidity is estimated with local acidification model. It is shown that the stable pitting growth for Zr60Cu25Al15 MG is considerably more favourable compared to Zr60Ni25Al15, because of its more rapid pit growth rate and more aggressive pit solution.; By the artificial pit electrode approach, growth behaviours of stable pits for melt-spun Zr60Ni25Al15 and Zr60Cu25Al15 metallic glasses (MGs) exposed to a 0.6 M NaCl solution are investigated.
