提出了在中性电解液NaNO3水溶液中采用电化学加工（ECM）法制备碳化钨（WC）合金微销的方法，并对加工条件进行了研究。通过改变电解液浓度、电流值和加工时间，实现了微针的加工。实验研究了超声波洗涤去除副产物的效果。在400 mA恒流条件下，在2.5 min的极短时间内获得了直径约20 μ m、长度约2 mm、宽高比约100的微引脚。
In this study, the fabrication of micro-pins made of tungsten carbide (WC) alloy with the electrochemical machining (ECM) using a neutral electrolyte, NaNO3 aqueous solution, was proposed and the machining conditions were investigated. The micro-pin fabrication was carried out by changing the electrolyte concentration, the current value and the machining time. The effect of the by-product removal by means of ultrasonic washing was investigated experimentally. The micro-pin with the diameter about 20 A mu m, the length about 2 mm and the aspect ratio about 100 was obtained under the constant current 400 mA in a very short time of 2.5 min.
