Hi, Roberta. Please try to get hold of a copy of the Electroplating Engineering Handbook [on AbeBooks or eBay or Amazon] , which has a good chapter on electropolishing. I believe that kovar can be treated as stainless steel for this particular application. A good way a metal finishing intern can use the internet is "trust but verify" :-)

how fine of a surface finish were you able to obtain on the kovar products from electroplating? I'm working on a project for my school and we are looking at attempting a similar procedure. thanks.
