Abstract

The invention discloses a solution for electrochemical deburring and oxide layer removal of a tantalum-foil material primary emitter for a magnetron and a deburring method. The solution is prepared from the following raw materials: 400mL/L to 450mL/L of nitric acid, 160mL/L to 180mL/L of hydrofluoric acid, 70mL/L to 90mL/L of phosphoric acid, 10mL/L to 15mL/L of glycerol, and 0.3g/L-0.4g/L of lauryl sodium sulfate. According to the structural characteristic that the thickness of the tantalum-foil material primary emitter of the magnetron is only 10-20 microns, the composition and concentration of an electrolyte are screened by use of lots of experiments; the electrolyte is capable of well removing the burrs and oxide layers on the edges and surface of the tantalum-foil material primary emitter for the magnetron and capable of meeting the assembly requirements of the high-precision cathode emitter, and has an important application value; as a result, the defects of the prior art can be solved.

Description

technical field [0001] The invention designs an electrolyte solution, in particular to a solution for electrolytic deburring and oxide layer removal of a tantalum foil material primary emitter for a magnetron and a use method thereof. Background technique [0002] The primary emitter is an important component of the magnetron. During the wire-cutting preparation process of the primary emitter of the tantalum foil material used for the magnetron, an oxide layer and burrs that appear during the wire-cutting process are prone to occur on the edge of the emitter. Due to the magnetron The thickness of the primary emitter of tantalum foil material is only 20μm-30μm, and the diameter is only φ3. The general electrolytic process cannot electrolytically remove the edge burrs and oxide layer of the emitter of this size, which will easily lead to excessive corrosion of the emitter itself and reduce the emission. As a result, the launch cannot meet the high-precision and high-performanc...
