  • Publication number: 20230312409
    Abstract: The present document discloses a glazing in the form of a window glass or vehicle glass which comprises a transparent glass substrate, and a coating, which comprises at least one functional metal Ag alloy coating layer. The alloy coating layer consists essentially of Ag with an alloying agent selected from a group consisting of Mg, Al, Si, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ge, Zr, Nb, Mo, In, Sn, Hf, Ta or W. An alloying agent concentration is 0.15-1.35 at. %, preferably 0.20-1.00 at. % or 0.25-0.80 at. % of the Ag alloy coating layer, the rest being Ag, and the Ag alloy coating layer has a thickness of 5-20 nm, preferably 8-15 nm or more preferably 8-12 nm.

  • Publication number: 20230202913
    Abstract: The present document discloses a glazing in the form of a window glass or vehicle glass which comprises a transparent substrate, and a coating. The coating comprises, in order outward from the transparent substrate, an optional diffusion barrier layer, a first anti-reflective layer, an optional first seed layer, a first functional metal layer, at least one optional first blocker layer, a second anti-reflective layer, an optional second seed layer, a second functional metal layer, at least one optional second blocker layer, a third anti-reflective layer, and an optional top layer, wherein at least one of the first functional metal layer and the second functional metal layer comprises a Ag alloy consisting essentially of Ag with an alloying agent selected from a group consisting of Li, C, Na, Mg, Si, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ge, Sr, Y, Zr, Nb, Mo, Rh, Pd, In, Sn, Sb, Hf, Ta, W, Pt or Au.

  • Patent number: 11408065
    Abstract: At least one layer in a coating located on a surface of a substrate is a domain structure layer constituted of two or more domains different in composition and a thin layer located between the domains and being different in composition from each of the domains. The thin layer is located between any one domain and any another domain and in contact therewith. When the size of each of a plurality of first domains present in the domain structure layer is defined as a diameter of a virtual circumcircle in contact with each first domain, the average value of the size of each first domain is not smaller than 1 nm and not greater than 10 nm and a thickness of the thin layer in a direction of thickness of the domain structure layer is not less than 1 atomic layer and not more than 10 atomic layers.
