Electropolishing for Nitinol wires 

-

My name is Emanoel R. of Almeida, and I work in a parts factory for use orthontics. I seek information on equipment and composition of the electrolyte for polishing of Nitinol (Ni-Ti alloys). Some attempts, in laboratory equipment, presented embrittlement, probably due to nascent hydrogen. Any information is of a lot of help. Thank you advance / Best Regards.

Nitinol is subjected to hydrogen embrilttlement. Bake after your process for 30 minuteas @ 400 F. You will be ok again.
