Introduction
Electropolishing removes a small but finite amount of metal from the surface that, in addition to
smoothing and brightening, produces a hygienically clean surface desirable for use by manufacturers of
food processing and medical equipment.
In addition to improved passivation, electropolishing provides many other benefits. Some examples
are surface stress relief, removal of surface carbon and oxides and reduction of friction. Hydrogen
embrittlement of articles is not produced during the electropolishing process, which takes minutes to
perform.
The quality of passivation depends on the type of stainless steel, the formulation of the electropolishing
solution and the conditions of operation. Free iron on the surface of the stainless steel is removed
resulting in improved corrosion resistance. No further chemical treatment is necessary in order to
passivate the stainless steel surface. Surface smoothing obtained by electropolishing also improves
passivation.
