Abstract
A process for electropolishing metals and metalloids and their alloys, intermetallic compounds, metal-matrix composites, carbides and nitrides in an electrolytic cell utilizing an externally applied magnetic force to enhance the dissolution process. The electropolishing process is maintained under oxygen evolution to achieve an electropolished surface of the work piece exhibiting reduced microroughness, better surface wetting and increased surface energy, reduced and more uniform corrosion resistance, minimization of external surface soiling and improved cleanability in shorter time periods.
