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.

In these investigations, an attempt has been made to correlate the deposition parameters of the reactive cathodic arc evaporation with processes at the surface of the composite Al—Cr targets and the nucleation and phase formation of the synthesized Al—Cr—O layers. The oxygen partial pressure and the pulsed operation of the arc current influence the formation of intermetallic phases and solid solutions at the target surface. The nucleation of the ternary oxides at the substrate site appears to be, to some extent, controllable by the intermetallics or solid solutions formed at the target surface. A specific nucleation process at substrate site can therefore be induced by the free choice of target composition in combination with the partial pressure of the oxygen reactive gas. It also allows the control over the oxide island growth at the target surface which occurs occasionally at higher oxygen partial pressure. This hypothesis is supported by the X-ray diffraction analysis of the layers as well as of the target surface.

摘要:
A pressure sensitive adhesive (PSA) is used to attach a plurality of wedge-shaped glass filter segments on a first side to a hub during the color ring build portion of the color wheel fabrication process. A strong adhesive, such as epoxy, is then used to adhere a second side of the filter segments directly to a turning surface of a motor, completing the color wheel fabrication. The epoxy is cured if necessary. The pressure sensitive adhesive can temporarily align the plurality of color filter segments in an alignment. The adhesive between the filter segments and the turning surface can then permanently bond the color filter segments in the alignment.
