Badania powierzchni stopu aluminium 2017A polerowanej elektrolitycznie

Abstract

Electropolishing is a method of removing roughness on metallic surfaces. Effectiveness and quality of the process depend on a lot of factors. This work includes results of investigation of electropolished 2017A aluminum alloy. Voltage 30V to 50V caused effective polishing. The best surface quality was reached applying parameters: 50V, 10 s time of polishing, 20°C electrolyte temperature. Large flow of electrolyte, less then $0,8 cm^2$ of polishing surface and no 1200 send paper grinding before polishing should be applied. Moreover, DIC Nomarski method of investigation of electropolished metallic surfaces was the most useful.
