文摘

An in situ investigation of metal dissolution during anodisation of Nb was performed. A constant dissolution rate during potentiodynamic Nb oxide growth was observed. A time-dependent dissolution was identified during potentiostatic anodisation of Nb. The Nb corrosion rate is dependent on potential in the potentiostatic oxide growth regime.
