Method for producing an anti-infective coating on implants

摘要

The invention relates to a method for producing an anti-infective coating on implants that contain titanium or are composed of titanium. The aim of the invention is to provide a coating method with which it is possible, for implants made of titanium or that contain titanium, to combine the optimization of the mechanical properties achieved with the anodic oxidation type II with the optimization of the anti-infective properties. According to the invention, the implants are anodically oxidized in an alkaline solution, then metal having anti-infective properties is electrodeposited on said surface, and afterwards the oxide layer containing metal is solidified.

主权项

1. A coated implant comprising
a substrate having a surface; and an anti-infective coating on the surface of the substrate; wherein the substrate titanium; wherein the anti-infective coating comprises a titanium oxide layer and particles of an anti-infective metal connected to the titanium oxide layer; wherein the titanium oxide layer comprises a conversion layer and a porous titanium oxide layer on the conversion layer formed by anodic oxidation of the substrate surface in an alkaline electrolyte solution; wherein the particles of the anti-infective metal are electro-deposited in the porous titanium oxide layer and the porous titanium oxide layer containing the anti-infective metal is solidified by blasting to form island-like anti-infective metal particles connected to said titanium oxide layer.
