Electropolishing of copper in orthophosphoric acid solution

+++++

Hi, I need your help to find a theoretical data about electropolishing of copper, I need it to finish my graduation project, I've done my experimental part of the project, the main aim of my project is to find the effect of concentration, anode diameter & temperature on the limiting current so the rate of electropolishing.

With the experimental work done, what results did you get, Joe?

You probably now need to do a computerized search of the published literature. But I see on the net a reference to an article "Electrolytic polishing of copper in orthophosphoric acid", (Australia. Council for Scientific and Industrial Research. Division of Tribophysics. Physical metallurgy report) by R. W. K Honeycombe, and maybe you can track down a copy of that. There is a lot about electropolishing, but only a little about electropolishing of copper, in ASM Metals Handbook Vol. 5 "Surface Engineering" and the Electroplating Engineering Handbook. Good luck!
