Fixing oxidation of stent after vacuum failed in annealing



December 6, 2011

During stent annealing process vacuum failed before completing the process. We found rough oxidation on stent surface instead of shiny grain. How can we remove oxides from the stents before electropolishing? Or any method by electropolishing?

Hi, Rohit.

What kind of "stent" is this that you wish to remove the oxidation from? Surely it can't be a medical stent that suffered a vacuum failure during annealing and you intend to use anyway?
