Abstract
The present invention relates to a method for improving the wear resistance of dyed surgical instruments having a vacuum-resistant material as the main body which, over the course of a vacuum coating step, is coated with a thin layer of titanium, and the coated surface is subjected to anodic oxidation. The method is characterized in that, over the course of the vacuum coating step, prior to coating with the layer of titanium, at least parts of the main body are coated with a layer of hard material which improves the wear protection.
