Study on electrochemical polishing of TC4 alloy

Using an environmentally friendly acid-alcohol system solution for electrochemical polishing of 3D printed titanium alloy, a typical U-I polarization curve was obtained, and explained the mechanism of electrochemical polishing. In this paper, the influence of electrochemical polishing factors (electrolyte temperature, polishing distance, and polishing time) on the surface roughness of Ti-6Al-4V (TC4) was studied, and optimized the process parameters to obtain a surface roughness of 0.3 mu m (1 mm x 1 mm). Electrochemical polishing can reach the level of mechanical grinding and polishing, meeting the requirements for subsequent assembly and use.

Automated summary

By using an environmentally friendly acid-alcohol system solution for electrochemical polishing of 3D printed titanium alloy, this study investigated the impact of electrochemical polishing on surface roughness and optimized process parameters to achieve a surface roughness comparable to mechanical grinding and polishing, meeting the requirements for subsequent assembly and use.
