agent for protection of nickel-based alloys from exposure to aggressive media, more particularly cermet coatings used for protecting power unit structures. SUBSTANCE: powder blend comprises, wt %: barium oxide, 12-14; boron oxide, 6.0-6.6; aluminum oxide 8.0-8.8; cerium oxide, 20- 22; zirconium oxide, 2.5-3.0; and nickel the balance. EFFECT: serviceability and reliability of nickel alloy components when exposed to cyclic effect of high velocity flow of oxidative generator gas containing solid particles at temperatures up to 750 C. 2 tbl
