Abstract: The properties of KCl-Ag/AgCl reference microelectrode, chloride ion selective microelectrode and tungesten microelectrode have been investigated. Preliminary results show that reference microelectrode has a stable potential with a small coefficient of temperature. In the absence of other halide (?)ons, the potential of ehloride ion selective microelectrode bears a linear relationship with logac(?) The change in the solution acidity and the presence of other ions have less effect on the linear relationship. Under acid conditions, the tungesten mjcroelectrode in NaCl or MgCl_2 solution have a stable potential which is quite linear with the pH value of the solution and is independent of the solution concentration. Other (?)ons existing in the solution in low concentration, do not affect the linear relationship. Some results have been obtained when the microeiectrodes in crevice corrosion and stress corrosion cracking studies and agreed well with the results obtained by other methods.
