Frequently Asked Questions About Nitinol Electropolishing

  • Can you electropolish nitinol?
    Electropolishing effectively improves nitinol surface quality, increasing smoothness and corrosion resistance. It’s an electrochemical process crucial to enhancing biocompatibility, especially in medical applications.
  • What effect does electropolishing have on nitinol?
    Electropolishing has several positive effects on nitinol. It results in a smoother surface finish, enhancing the aesthetic and functional qualities of the material. It also improves nitinol’s corrosion resistance by removing surface contaminants and oxides.
  • What’s the difference between electropolishing and passivation?
    While they’re both surface treatment processes, electropolishing offers a broader range of benefits. Electropolishing is an electrochemical method that smooths a metal’s finish, corrosion resistance, and biocompatibility. On the other hand, passivation is a chemical process that removes free iron and iron compounds. Electropolishing is thirty times more effective than passivation for preventing corrosion.
