Electropolishing

Electropolishing is an electrochemical process that removes a surface layer normally around 20/30 microns.

To perform electropolishing, an acid bath is used containing sulfuric and phosphoric acid, and is subjected to a continuous flow of electrical current.

The part to be treated will be the anode (the positive pole) and with hooks, pliers or other specific tools it will be connected to the cathode (the negative pole). The process is exactly the opposite of placing chromium or nickel and that is the reason why we call ourselves atypical galvanics because we do not use metals in our processes.

In the electrochemical process for stainless steel, nickel and iron are removed more quickly, leaving the surface rich with chromium: this treatment improves the surface layer of stainless steel.

The timing for the parts to be treated are different depending on the thickness, size, and the physical appearance result to be obtained.

With the electrolytic treatment items of various shapes and sizes can be treated, reaching parts that would otherwise be difficult to reach with other processes.

Electropolishing is used in many industries, especially where corrosion resistance, cleanability and smoothness of stainless steel are important qualities.
