FIELD: machine building.
SUBSTANCE: invention relates to means of protecting parts from nickel-base alloys for turbines of liquid rocket engines. Coating contains nickel, barium oxide, cerium oxide, boron oxide, aluminum oxide, zirconium oxide, silicon oxide, titanium oxide and potassium and sodium oxides, with the following ratio of components, wt%: 40–55 of nickel, 13–16 of barium oxide, 14–16.6 of cerium oxide, 10–13 of boron oxide, 5–8 of aluminum oxide, 1–2 of zirconium oxide, 2–4 of silicon oxide, 0.05–0.15 titanium oxide, 0.05–0.15 potassium and sodium oxides.
EFFECT: higher operating characteristics of coating.
