Abstract

The emissivity factors of the coatings based on high-temperature enamels EVT-24 and KO-818 with the addition of Co₂O₃ and, B₄Si at temperatures of 293–1173 K are experimentally studied. Metal coatings with a high emissivity factor in the wavelength range λ = 0.75–10.0 μm are developed; they have the following compositions (wt %): 70 KO-818 + 30 B₄Si, 50 EVT-24 + 50B₄Si, and 50 EVT-24 + 50 Co₂O₃.
