Selenium Surface treatment (S2T)


3 possibilities for coloured, resistant and protected titanium

We offer titanium anodisation through processes developed and validated by our expert team as per IQ OQ PQ PPQ, in accordance with the requirements of ISO 13485 and 21 CFR820s.

This concerns electrochemical processes leading to formation of a titanium oxide layer on the surface of products, granting the materials enhanced resistance to wear and corrosion.

In addition to protecting medical devices, these processes make it possible to colour them (without colouring agents or pollutants) thanks to the phenomenon of interference and crystallographic orientation of the oxide formed, while enhancing their biocompatibility through modification of surface polarity.

We place our in-house expertise at your service via our three titanium anodisation solutions ensuring reproducible results coupled with the perfect biocomptability of the implants.

Type I anodisation: The colour of the natural oxide surface layer is replaced by a crystallographically oriented oxide layer, granting materials enhanced resistant to wear and corrosion while assigning the products treated a distinct colour, so facilitating identification of devices. Thanks to our expert knowledge of the process and the interference phenomenon, we can offer over 50 different colours in a perfectly controlled and reproducible manner.

Type III anodisation (SHINE anodisation): Our surface preparation process ensures that the natural oxide layer on the surface of products is reactivated without being stripped, so allowing its crystallographic orientation to be controlled during the anodic oxidation reaction. In addition to the colouring and enhanced protection of the material and its wear resistance, this process enables the shiny appearance of products to be retained with no loss in material. Our type III anodisation solution is also offered with over 50 colour references.

Type II anodisation: This anodisation solution leads to the formation of a single-colour (anthracite grey) oxide layer with mechanical properties which are far superior to those obtained by coloured anodisation (higher scratch resistance, reduced friction forces and an increase in scratch hardness of around 15%). This process further improves the biocompatibility of medical devices through enhanced bonding of the bone to the coating thanks to modification of its polarity and porosity.
