Developing new technique is essential for acquiring new knowledge in corrosion study. One of the most powerful non-electrochemical techniques that have been developed recently is the scanning probe microscopy (STM, AFM, KFM, SNOM and etc.). Beside this technique, QCM, SECM, SVET are often used in corrosion study. In present paper, the problems when we use STM, AFM, KFM, QCM and SECM are mainly discussed.
