介绍了一种利用电解液喷射加工硬质合金的新方法。采用NaN3水溶液作为电解液，取代了硬质合金电解加工中常用的NaN3和NaOH混合水溶液，但该混合水溶液具有危险性。在交流电(AC)和直流(DC)的共同作用下，成功地进行了加工。然而，AC比DC能够在喷射下实现更多的局部溶解。为防止喷嘴磨损，交流加工采用了绝缘体喷嘴。由于溶解更加局部化，因此对DC加工也很有用。
This paper describes a new method to electrochemically machine cemented tungsten carbide using electrolyte jet machining (EJM). NaNO 3 aqueous solution was used as the electrolyte instead of a mixed aqueous solution of NaNO 3 and NaOH, which is normally used for the conventional electrochemical machining (ECM) of cemented tungsten carbide, but has hazardous characteristics. The machining was carried out successfully with both alternating current (AC) and direct current(DC). However, AC enabled more localized dissolution under the jet than DC. An insulator nozzle was employed for AC machining to prevent the nozzle wear. It was also useful for DC machining because dissolution was more localized.
