When it comes to electropolishing Nitinol, it’s important to know how to electropolish Nitinol at room temperature compared to electropolishing Nitinol at very low temperatures. Here are some things to keep in mind when electropolishing Nitinol at different temperatures.

Electropolishing is a process used to remove materials from a metallic surface (in this case medical implant devices) to provide a level surface finish. Some of these surfaces including nitinol, cobalt chrome and titanium alloys. Electropolishing allows for less rejection of medical implant devices. Here are at RBP we offer a variety of electropolishes for the medical implant device industry. Here are some of the electropolishes we offer.

To ensure the effectiveness of medical implant devices it is essential that manufacturers correctly clean, deoxidize, polish and passivate these devices. Here is some relevant background pertaining to these processes.

Minimum recommended process for electropolishing Titanium alloys
- Clean in MicroClean Ti™ (RDZ-1849) (Time and temperature to be determined, no such thing as “too much”)
- Water Rinse
- Alcohol Rinse
- ElectroPolish Ti2 (RDZ-1676), 300+ Amps/ft2, up to 10 minutes
OR
Generic Electropolish (70/30 Methanol/sulfuric) which you can make, or can purchase Nitinol Titanium ElectroPolish (RDZ-1867), used at 7-10 volts, ~50 Amps/ft2, and below -20 degrees C. If you are making this exciting blend, you may want to read “Control of Methanol-Sulfuric blends”.
If the polishing is non-uniform, the surface may be oxidized, and require a treatment after the MicroClean Ti™: MicroClean MV™ (RDZ-1995), which, although it is a strong acid de-oxidizer it will NOT remove metal.
