spark erosion

From thermodynamics, the electrode erosion process of high-power gas spark gap switch is analysed in theory.

从热力学的角度，对高功率气体火花开关的电极烧蚀过程进行了理论分析，建立了该烧蚀过程的简化数学模型并进行了数值求解；

Thus, spark erosion of die material reproduces the contour of the electrode in the die block.

因此, 模具材料被电火花腐蚀后,在模块中形成了电极的空间形状.

Fine thermocouple with tip diameter less than 0.02 mm was fabricated from commonly available couple wires ( diameter 0.1 mm) under the monitoring of a microscope and by way of electrochemical erosion and spark welding.

尝试在显微监视条件下通过电解腐蚀方法，用直径100μm的普通热电偶丝制作尖端直径小至10-20μm的微细偶丝，经电火花焊接形成微细热电偶。
