Letter 23019 Electropolishing platinum-iridium alloys [California]+++ I am interested in learning how to electropolish platinum-iridium alloys (Pt - Ir). I would appreciate any suggestions on what electrolyte, voltages, current densities, and cathode material to use for my project. Is a pretreatment required prior to electropolishing? Jim Carlson
+++ Dear Jim, This question has been asked before on this website. I don't know of any electropolishing methods currently used for platinum or platinum alloys. For a large amount of information on working with platinum, you may want to check the Platinum Guilds technical website www.pgi-platinum-tech.com . Good luck, Jim Sivertsen
++++ Hi Jim, I'm looking for an EP process (for PtIr 80/20), Do you already find a proper solution? Regards, Oded NISSAN
Dear Reader: please choose what you want to do--
