Abstract: The present invention allows simple and sensitive detection of microimpurities, microdefects, and corrosion starting points which may be present in a material. A probe microscope has a function to sense ions diffused from a specimen in a liquid. A probe is caused to scan over a predetermined range on a specimen. Then, the probe is fixed to a particular position in a liquid so as to set the distance between the specimen and the probe to a given value at which the microstructure of the specimen surface cannot be observed. Thereafter, one of the current between the probe and a counter electrode and the potential between the probe and a reference electrode is controlled, and the other of the current and potential which varies in accordance with the control is measured. Thus, ions diffused from the specimen are sensed.

Abstract: This invention relates to an improved apparatus and method for electrolytic descaling of steel strips. The apparatus comprises electrodes integrated with nozzles having jet openings for dispensing electrolyte onto the surface of the steel strips. By jetting the electrolyte to the steel strip in the air and applying a voltage to the electrode, the scale on the surface of the steel strip is removed. This jetting of electrolyte reduces the size requirement of the electrolyte tank storing the electrolyte because the required quantity of electrolyte decreases. The present invention does not require immersion of the electrodes in the electrolyte and thus avoids the problem of short-circuiting that occurs with submerged electrodes. This results in a significant improvement in electric power efficiency.
