Porous alumina films had been fabricated by anodizing from aluminum films after an electropolishing procedure. Alumina stripes without pores can be distinguished on the surface of the porous alumina films. The width of the alumina stripes increases proportionally with the anodizing voltage. And the pores tend to be initiated close to the alumina stripes. These phenomena can be ascribed to the e...

The reduction of surface roughness on additively manufactured components has become a critical factor in engineering applications. This paper reports the electropolishing Ti-6Al-4V by powder bed selective laser melting (SLM) using nontoxic electrolyte solution. results have shown that salt-based can be used to electropolish titanium alloys. waviness as-built alloy was reduced five times average...

Material removal rate in electropolishing is often overlooked because this process generally addressed for surface finish; however, it paramount on metallic sheet machining possessed with intricate geometry. Electropolishing removes material from the of a workpiece based anodic dissolution process. The depends current density, electrolyte, strength magnetic field, polishing time and temperature...
