  • Patent number: 11875976
    Abstract: The present invention relates generally to a plasma source utilizing a macro-particle reduction coating and method of using a plasma source utilizing a macro-particle reduction for deposition of thin film coatings and modification of surfaces. More particularly, the present invention relates to a plasma source comprising one or more plasma-generating electrodes, wherein a macro-particle reduction coating is deposited on at least a portion of the plasma-generating surfaces of the one or more electrodes to shield the plasma-generating surfaces of the electrodes from erosion by the produced plasma and to resist the formation of particulate matter, thus enhancing the performance and extending the service life of the plasma source.
    Type: Grant

  • Patent number: 8512883
    Abstract: A low-emissivity multilayer coating includes, in order outward from the substrate, a first layer including a layer containing titanium oxide, a layer containing silicon nitride, or a sublayer layer containing titanium oxide in combination with a sublayer containing silicon 5 nitride, a second layer including Ag, a third layer including at least one layer selected from titanium oxide layers and silicon nitride layers, a fourth layer including Ag, and a fifth layer including silicon nitride, where the color of the coatings can be varied over a wide range by controlling the thicknesses of the layers of titanium oxide, silicon nitride and Ag.

  • Patent number: 7632572
    Abstract: A low-emissivity multilayer coating includes, in order outward from the substrate, a first layer including a layer containing titanium oxide, a layer containing silicon nitride, or a sublayer layer containing titanium oxide in combination with a sublayer containing silicon nitride; a second layer including Ag; a third layer including at least one layer selected from titanium oxide layers and silicon nitride layers; a fourth layer including Ag; and a fifth layer including silicon nitride. The color of the coatings can be varied over a wide range by controlling the thicknesses of the layers of titanium oxide, silicon nitride and Ag. A diffusion barrier of oxidized metal protects relatively thin, high electrical conductivity, pinhole free Ag films grown preferentially on zinc oxide substrates. Oxygen and/or nitrogen in the Ag films improves the thermal and mechanical stability of the Ag.

  • Patent number: 6679978
    Abstract: A photocatalytically-assisted self-cleaning (“PASC”) coating on a substrate enables the substrate to shed dirt simply by rinsing with water. A method of making a PASC coating includes depositing by chemical vapor deposition an alkali metal diffusion barrier layer on a substrate; sputtering an ultraviolet radiation activated layer on the alkali metal diffusion barrier layer at a temperature of 100° C. or less; and, without heating above 100° C., exposing the ultraviolet radiation activated layer to ultraviolet radiation to form the self-cleaning substrate. The sputter deposition of the ultraviolet radiation activated layer on the chemical vapor deposited alkali metal diffusion barrier layer allows the ultraviolet radiation activated layer to be activated upon exposure to UV radiation without first having been heated during and/or after deposition.
