Electropolishing is a finishing process done with the help of chemicals to remove thin layers of materials from any metal part. To be exact it is majorly used to give a shiny, smooth surface finish to stainless steel and other similar alloys. An electropolishing machine helps achieve a smooth surface in case of fragile and complex geometries.
Electropolishing is basically a type of reverse electroplating in which electrical current is used to remove a thin layer of metal ions from the electrical surface. The things needed in case of electropolishing are;
- An electrolyte solution
- 170 degree to 180° temperature of the electrolyte
- An ideal time of exposure to the electrical current
- The density of the electrical current should be between 140 to 250 amps.
- Proper composition of the alloy
Working on electropolishing machines
- While going with the electropolishing technique, the parts of the metal serve as positively charged anodes. Another negatively charged Cathode is also there, which is generally made up of Stainless Steel material and connected to the negative terminal of the power supply.
- Both the cathode and anode have particular temperatures controlled by the electrolyte. After this, an electrical current runs from the anode to the cathode with the help of the electrolyte solution. With the help of this electropolishing machine, the thin layers on the surface of the material get dissolved in the electrolyte solution. Therefore the material surface gets removed giving it a new Shine and smoothness.
Thus, helping us to your all odds from metals.
