GLASSWARE WITH SPRAYED COATING AND METHOD OF FORMING OF COATING Russian patent published in 1997 - IPC

FIELD: architectural-structural glass. SUBSTANCE: glassware with a sprayed coating uses a glass backing with a layer structure applied onto it, including sublayer of Si₃N₄,, first layer of nickel or its alloy, layer of silver, second layer of nickel or its alloy and upper layer of Si₃N₄,, with the glass backing being 2-6 mm thick, it has a visible light transmissivity at least of 78%, normal emissive power value E_n not exceeding 0.12 and hemispherical emissive power value E_n not exceeding 0.16 due to selection of the respective thickness of layers and method of fabrication consisting in forming of sublayer Si₃N₄ in an atmosphere containing nitrogen, forming of the first layer of the alloy of nickel, forming of the silver layer, forming of the second layer of the alloy of nickel, forming of upper layer of Si₃N₄ in an atmosphere containing nitrogen; the alloy of nickel represents an alloy of nickel and chromium nitride; the first and second layers of the alloy of nickel and chromium nitride and the silver layer are formed in an atmosphere containing nitrogen within 25-100 volume percent. EFFECT: enhanced quality. 29 cl, 8 tbl, 4 dwg
