  • Publication number: 20230271877
    Abstract: A low-E (low emissivity) coating includes a multilayer overcoat designed for reducing fingerprints. The multilayer overcoat includes a layer comprising an oxide of zirconium (e.g., ZrO2) sandwiched between and contacting first and second layers of or including silicon nitride (e.g., Si3N4, SiOxNy, SiZrOxNy, or the like). The uppermost layer comprising silicon nitride modifies the surface energy of the layer comprising the oxide of zirconium so as to make the uppermost surface of the coating more hydrophilic, thereby reducing or minimizing interaction between zirconium oxide and finger oil to reduce fingerprints on the uppermost surface of the coating.

  • Patent number: 11498867
    Abstract: A coated article incudes a low-emissivity (low-E) coating having at least one infrared (IR) reflecting layer of or including a material such as silver or the like. The low-E coating is designed so that the coated article can realize a low U-value in combination with a high solar heat gain (g value). In the top dielectric portion of the coating above the silver, a high-low-high refractive index sequence is provided. This allows for a low U-value and a higher g value to be obtained for a given silver thickness. Coated articles herein may be used in the context of insulating glass (IG) window units, or in other suitable applications such as monolithic window applications, laminated windows, and/or the like.

  • Patent number: 11236014
    Abstract: Certain example embodiments relate to ultra-fast laser treatment of silver-inclusive (low-emissivity) low-E coatings, coated articles including such coatings, and/or associated methods. The low-E coating is formed on a substrate (e.g., borosilicate or soda lime silica glass), with the low-E coating including at least one sputter-deposited silver-based layer, and with each said silver-based layer being sandwiched between one or more dielectric layers. The low-E coating is exposed to laser pulses having a duration of no more than 10?12 seconds, a wavelength of 355-500 nm, and an energy density of more than 30 kW/cm2. The exposing is performed so as to avoid increasing temperature of the low-E coating to more than 300 degrees C. while also reducing (a) grain boundaries with respect to, and vacancies in, each said silver-based layer, (b) each said silver-based layer's refractive index, and (c) emissivity of the low-E coating compared to its as-deposited form.

  • Patent number: 10882997
    Abstract: A coated article is provided with a low-emissivity (low-E) coating on a glass substrate. The low-E coating includes an infrared (IR) reflecting layer between at least a pair of dielectric layers. The IR reflecting layer may be of silver or the like. The coating is designed so as to provide a highly transparent coated article that is thermally stable upon optional heat treatment and which can be made to have a low emissivity in a consistent manner. The coating is designed to have improved IR reflecting layer quality, and thus reduced tolerances with respect to manufacturability of desired emissivity values. The coated article may be used in monolithic window applications, IG window applications, or the like.

  • Patent number: 10766808
    Abstract: This invention relates to a coated article including a low-emissivity (low-E) coating. In certain example embodiments, the low-E coating is provided on a substrate (e.g., glass substrate) and includes at least first and second infrared (IR) reflecting layers (e.g., silver based layers) that are spaced apart by contact layers (e.g., NiCr based layers) and a dielectric layer of or including a material such as silicon nitride. The dielectric layer is split by a layer of or including zirconium oxide, in order to improve durability. In certain example embodiments, the coated article has a low visible transmission (e.g., no greater than 60%, more preferably no greater than about 55%, and most preferably no greater than about 50%).

  • Patent number: 10696584
    Abstract: A coated article includes a low emissivity (low-E) coating supported by a glass substrate. The low-E coating includes at least one silver (Ag) based infrared (IR) reflecting layer(s) that is provided adjacent to and contacting at least one contact layer of or including Ag, Ni and Cr. The provision of a contact layer(s) including at least Ag, Ni and Cr, directly over and contacting a silver-based IR reflecting layer, has been found to advantageously increase visible transmission (Tvis) of the low-E coating. Such low-E coating may be used in applications such as monolithic windows, insulated glass (IG) window units, and the like.

  • Patent number: 10611678
    Abstract: In certain example embodiments, a coated article includes a carbon-doped zirconium based layer before heat treatment (HT). The coated article is heat treated sufficiently to cause the carbon-doped zirconium oxide and/or nitride based layer to result in a carbon-doped zirconium oxide based layer that is scratch resistant and/or chemically durable. The doping of the layer with carbon (C) has been found to improve wear resistance.
