Introduction

To obtain high quality electropolished finishes on most stainless steel alloys, it is necessary to process the work through three major operations:

Metal Preparation: To remove surface oils, greases, oxides, and other contaminants which interfere with the uniformity of electropolishing.

Electropolishing: To accomplish the desired smoothing, brightening, and/or deburring of the metal, followed by recapture of the electrolyte to minimize waste treatment.

Post Treatment: To remove residual electrolyte, to remove byproducts of the electropolishing reaction, and to dry the metal to prevent staining.

Each of these major operations may consist of several tank stations to accomplish the desired result. The typical flow chart is shown in the following schematic diagram:
