Abstract

The present invention proposes a diversion method for improving concentration polarization when a microwave regular metal waveguide is gold-plated. ; Fix the microwave regular metal waveguide to the electroplating rack; make the small diameter part of the guide device and the microwave regular metal waveguide cavity be in the same axial direction, and be fixed at a certain distance from the electroplating rack to form an electroplating whole; After the electroplating gold pretreatment step, the electroplating whole is immersed in the electroplating gold solution; the electroplating whole and the electroplating gold solution are relatively moved. The present invention realizes the purpose of improving the concentration polarization during the gold plating of the microwave ruled metal waveguide, improves the deposition speed of the electroplating gold layer during the gold plating of the microwave ruled metal waveguide, improves the production efficiency, and improves the gold plating layer of the microwave ruled metal waveguide the quality of.

Description

technical field [0001] The invention relates to the field of waveguide processing, in particular to a current guiding method for improving concentration polarization when a microwave regular metal waveguide is plated with gold. Background technique [0002] Microwave regular metal waveguides have the advantages of small loss, large power capacity, no radiation loss, simple structure, and easy manufacture. They are widely used in microwave communications, radar, and especially high-power, high-frequency precision test systems. In the process of waveguide processing and molding, in order to reduce the loss of microwave signal transmission and improve the conductivity, corrosion resistance and weldability of the inner wall of the waveguide, a gold plating process is generally adopted to electroplate a layer of gold on the surface of the microwave regular metal waveguide. In order to ensure the thickness and quality of the electroplated gold layer in the waveguide cavity, it is ...
