Low emissivity coating comprising a layer of silver and an absorbing barrier layer of nickel chromium oxide, NiCrOx

摘要

Disclosed is a low-emissivity coating on a substrate, the coating consisting essentially of, in order outward from the substrate: a) a first dielectric layer; b) a first nucleation layer; c) a first Ag layer; d) a first absorbing barrier layer consisting essentially of an oxide of nickel and chromium, wherein the first absorbing barrier layer comprises about 15 to 60 atomic percent oxygen; e) a second dielectric layer; f) a second nucleation layer; g) a second Ag layer; h) a second absorbing barrier layer; i) a third dielectric layer; and j) optionally, a topcoat layer, wherein the coating has a visible transmission of less than about 69%.
