| Research Abstract |
New micro-electrochemical techniques developed were applied to investigate the mechanism and kinetics of heterogeneous reaction of the interface between practical materials and environment. Though a probe nano-electrode was successfully developed by using LIGA, the development of a scanning electrochemical nano-scope could not be completed because of the difficulty of probe alignment. However, the application of a coaxial double microelectrode to SECM probe was successfully attained the improvement of sensitivity and lateral resolution of SECM image. Application of this SECM and amicro-electrochemical cell technique to in situ observation of polycrystalline iron surface corroding in acidic sulphate media revealed that iron corroded heterogeneously depending on crystallographic orientation which affected the hydrogen evolution reactivity. The stability of passive state on iron was also strongly dependent on the substrate orientation.
