FIELD: technological processes.
SUBSTANCE: invention relates to energy-saving coatings, in particular to energy-saving coatings on glass, having properties of thermal stability and high selectivity, and a method for production thereof. In particular, a heat-resistant highly selective energy-saving coating of bronze color on glass is proposed, which consists of separate directly contacting layers. Said coating includes the following adhering layers in the order from the glass substrate to the outside: the first layer containing the sub-stoichiometric nitride of silicon-doped Si-Al-N, the next layer being the first contact layer, which contains tin-doped zinc oxide Zn-Sn-O, followed by a layer containing zinc alloyed zinc oxide Zn-Al-O, which is the first catalytic layer, next layer, which contains Ag silver, is the infrared reflecting first layer, followed by a layer comprising a sub-stoichiometric nichrome oxide Ni-Cr-O, which is a first barrier layer, next layer, which contains Zn-Al-O zinc alloyed aluminum, is first covering layer, followed by an intermediate layer containing sub-stoichiometric aluminum nitride Al-N, next layer is second contact layer and contains tin-doped zinc oxide Zn-Sn-O, followed by a layer containing zinc alloyed zinc oxide Zn-Al-O, which is a second catalyst layer, next layer, which contains silver Ag, is the second layer reflecting infrared radiation, followed by a layer comprising a sub-stoichiometric nichrome Ni-Cr-O oxide, which is a second barrier layer, next layer, which contains sub-stoichiometric tungsten nitride W-N, is absorbing layer, followed by a layer containing sub-stoichiometric aluminum nitride Al-N, which is a second covering layer, as well as a protective layer for providing chemomechanical protection of the entire previously listed layer structure, next layer, which is an external layer of the above listed structure of the coating layers and acting as an anti-propagation cracks "PRT" layer, contains zinc alloyed zinc Zn-Sn-O.
EFFECT: technical result consists in provision of stability in relation to prolonged effects of high temperatures, which is expressed in maintaining minimum value of turbidity level of glass substrate based on results of exposure, sun-proof properties with respect to excessive thermal solar action with simultaneous maintenance of a satisfactory visible light transmission level, properties of energy efficiency in terms of reducing radiative heat losses during cold and bronze reflection of the surface of the glass substrate on the side opposite to the side on which the thin-film energy-efficient optical coating is applied, achieved in a wide range of viewing angles.
