technical field [0001] The invention designs an electrolyte, in particular to an electrolyte for tungsten helix electrolytic polishing and a method for electrolytic polishing using the electrolyte. Background technique [0002] The tungsten helix is ​​an important component of the slow wave structure in the traveling wave tube. The smoothness of the surface of the tungsten helix directly affects the performance of the traveling wave tube. If the surface of the traveling wave tube is uneven and has burrs, it will cause the heat dissipation of the traveling wave tube. Poor performance directly affects the performance of the traveling wave tube. The electrolytic polishing method used in the prior art has complex electrolyte composition, poor environmental performance, and unstable polishing process. It is also very high, so in the process of polishing, the requirements for polishing quality are very good. The polishing liquid and polishing process of the prior art cannot meet t...

[0002] The tungsten helix is ​​an important component of the slow wave structure in the traveling wave tube. The smoothness of the surface of the tungsten helix directly affects the performance of the traveling wave tube. If the surface of the traveling wave tube is uneven and has burrs, it will cause the heat dissipation of the traveling wave tube. Poor performance directly affects the performance of the traveling wave tube. The electrolytic polishing method used in the prior art has complex electrolyte composition, poor environmental performance, and unstable polishing process. It is also very high, so in the process of polishing, the requirements for polishing quality are very good. The polishing liquid and polishing process of the prior art cannot meet the working requirements of traveling wave tubes with high power, large working ratio and high precision requirements.
