The AESF has not published expanded technical information about electropolishing for morethan 30 years. The most recent AESF Illustrated Lecture on the subject, titled“Electropolishing,” was written by G.R. Schaer in 1971. In the last 30 years, electropolishing ofstainless steels has grown remarkably. Industries employing electropolishing now includemedical devices, surgical implants, food and beverage equipment, automotive, aeronautical andaerospace applications, pharmaceutical and biopharmaceutical industries, microelectronics,vacuum applications, and many others. A sub-committee of AESF’s Emerging TechnologiesCommittee (Electrochemical Metal Removal) has recognized the need for updated information toadvance the practice of electropolishing among its members. This paper is intended to review thestate of the art as last reported and to recommend a direction for continued study of the process.The paper will focus on modern issues related to electropolishing of stainless steels and willsuggest topics for future discussion through AESF’s technical subcommittee process.
