Electropolishing

Electropolishing is an advanced electrochemical surface treatment that enhances the performance and reliability of nitinol components. By removing a thin layer of material, the process smooths the surface, resulting in:

  • Improved finish
  • Superior corrosion resistance
  • Enhanced biocompatibility

In many cases, electropolishing also inherently passivates the part, though some customers may still request both processes depending on specific requirements.

Passivation

Passivation is a widely used surface treatment that improves the corrosion resistance of metals through chemical means. The process typically involves:

  • Thorough cleaning: removes unwanted surface materials

  • Oxide layer formation: develops a stable and protective oxide layer, primarily titanium dioxide, that enhances corrosion resistance and biocompatibility
