Electropolishing

Electropolishing is an advanced electrochemical surface treatment that enhances the performance and reliability of nitinol components. By removing a thin layer of material, typically 5-20% of the mass of the part, 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 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
