HEAT-RESISTANT COVER Russian patent published in 2018 - IPC C03C8/14 C03C8/12

Abstract RU 2661942 C1

FIELD: technological processes.

SUBSTANCE: invention relates to heat-resistant coatings. Heat-resistant coating contains, WT%: 12.0–20.5 of Al₂O₃; 3.0–8.0 of CaO; 0.8–3.0 of MgO; 6.0–11.0 of BaO; 2.0–5.0 of TiO₂; 5.5–10.0 of B₂O₃; 0.5–5.5 of SiB₄; 1.0–11.0 of 25BaO-25Al₂O₃-50SiO₂; SiO₂ – the rest being.

EFFECT: reduced difference between the operating temperature and the firing temperature of the coating, ensuring heat resistance and thermal resistance of the coating at the temperature of 1,250 °C and increased adhesion strength of the coating with heat-resistant nickel welded alloys at the room temperature.
