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
