  • Patent number: 10711341
    Abstract: 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.

  • Patent number: 9028956
    Abstract: A coated article is provided, having a coating supported by a glass substrate where the coating includes at least one color and/or reflectivity-adjusting absorber layer. The absorber layer(s) allows color tuning, and reduces the glass side reflection of the coated article and/or allows sheet resistance of the coating to be reduced without degrading glass side reflection. In certain example embodiments the absorber layer is provided between first and second dielectric layers which may be of substantially the same material and/or composition. In certain example embodiments, the coated article is capable of achieving desirable transmission, together with desired color, low reflectivity, and low selectivity, when having only one infrared (IR) reflecting layer of silver and/or gold. Coated articles according to certain example embodiments of this invention may be used in the context of insulating glass (IG) window units, monolithic windows, or the like.
