FIELD: chemistry.
SUBSTANCE: infrared reflector consists of a metal substrate, characterised by that it is coated with a layer of zirconium nitride and chromium nitride of general formula (ZrxCr1-x)1-yNy with x ranging from 0.15-0.7 and y ranging from 0.01 to 0.265. The method of production involves producing a metal substrate; depositing a layer of zirconium nitride and chromium nitride on said substrate by physical vapour deposition using a target which contains 15-70 wt % zirconium, with the remaining part consisting of chromium and impurities which are inevitable in the treatment process, and injecting nitrogen with a neutral carrier gas in ratio of 4/16 to 16/16 while simultaneously sputtering zirconium and chromium.
EFFECT: designing an infrared reflector, having high heat reflecting power and high resistance to high temperatures in corrosive or oxidative media.
