A Better Way to Electropolish Nitinol

It is common to electropolish Nitinol parts in a solution of sulfuric acid and methanol cooled to subzero temperatures, typically -30˚C to -50˚C.  This works, and it almost considered a standard method of electropolishing Nitinol and similar materials.  But working at these low temperatures is difficult.  Powerful chillers are needed.  It takes time to cool the solution.  Condensation issues and icing around the EP vessel need to be addressed.

Another way is to use a different electrolyte that is capable of delivering equivalent results under ambient conditions, at temperatures between 10˚C and 25˚C.  A simple chiller is used to maintain steady process temperature.  A setup is simple and quick.  Water condensation is avoided.

RBP offers such room temperature electropolishing solutions.  The existing offering is a great alternative to sulfuric/methanol.  And we are still actively working to make these electropolishes even better.
