Abstract
This paper describes a new polishing method in which electrolysis is combined with free-abrasive polishing to form mirror-like surfaces of stainless steel, aluminum, titanium and tungsten with roughness less than 1 nm Ra and flatness less than 1 μm. Removal rate in cases of stainless steel and tungsten increases with current density in wide ranges where mirror-like surfaces are formed. Eelectrolysis in cases of aluminum and titanium doesn't increase removal rates but it only contributes to forming mirror-like surfaces in narrow ranges of current density by means of controlling chemical activity of these metals.
