| Abstract | ||
| The rates of electropolishing copper cubiform surfaces in H3PO4 were studied undernatural convection conditions in a two-compartment cell. The following variables werestudied : anode shape and its dimensions ( cubiform ) , H3PO4 concentration, temperature andviscosity of polishing solution.The dimensions of cubiform of the anode were found to have no effect on the polishingcurrent density. Also it was found that the polishing current density to increase withdecreasing H3PO4 concentration and to increase with increasing temperature. The effect of thetemperature on the polishing current density was found to obey the Arrhenius equation withan activation energy of 4.9 kcalmol-1. The polishing current density was found to decreasewith increasing viscosity of electropolishing solution . | ||
