Type II
Anodization

Type II anodizing is an electrochemical process in which a defined oxide layer is applied to a metallic surface, replacing the thin natural oxide layer on the implant surface. This is achieved by a spark discharge generated on de the surface of the implant while it is immersed in an electrolytic bath. The discharge melts the implant surface and the oxide layer becomes a solid, integral part of the base material and reduces the risk of delamination.
