  • Electropolishing is a common technique for rendering a smooth mirror-like surface finish to implant materials. It is also known to improve a material's corrosion resistance. A current method to evaluate the corrosion resistance of biomedical implants is based on in-vitro corrosion tests (ASTM F2129-08). Cyclic polarization tests were conducted at 37 °C using phosphate buffer saline (PBS) as an electrolyte to evaluate the corrosion resistance of electropolished and non-electropolished Ni-Ti-Cu and Ni-Ti-Cr alloys. The effects of electropolishing on break down potential (Eb) and the difference between break down potential and rest potential (Er), which is equivalent to the resistance to pitting corrosion were evaluated. © 2009 Springer Berlin Heidelberg.
