Selenium Medical Implements Titanium Type II Anodizing


This type of anodizing results in the formation of an oxide layer with a single color, grey anthracite. It is applied to titanium alloy implants and instruments when the surface is subjected to friction, or mechanically stressed during use.

Process advantages include:

  • Improved mechanical and surface properties of medical devices, resulting in reduced wear, scratch resistance, increased fatigue, corrosion resistance, and greater hardness than color anodizing
  • Improved biological properties of medical devices such as improved grip of the bone, good biocompatibility and ease of removal after recovery
  • The treatment causes no dimensional change to medical devices

Selenium Medical R&D project manager Boussad Sebih said: "This process, not very developed in France, comes from our expertise and has been developed with all co-workers of the research and development division of Selenium Medical."
