抄録

<p>This paper suggests a novel method for the dynamic measurement and control of single-crystal tungsten micro-tip corrosion in order to address the problems of poor repeatability, low control precision, and the inability to set control tip diameters in the conventional single-crystal tungsten micro-tip electrochemical corrosion process. This technique begins by capturing experimental images using a video microscope, performing edge detection and contour searching to extract boundary information of the single-crystal tungsten micro-tip, and subsequently calculating and displaying the instantaneous tip diameter. Subsequently, a target diameter for the micro-tip is set, and when the detected value reaches this target, the software automatically cuts off the corrosion current. Experimental results demonstrate that this technique enables the production of high-quality single-crystal tungsten micro-tips with a diameter of approximately ⌀800 nm and exhibits excellent repeatability.</p>
