摘要: The invention relates to the field of producing the means for protecting the alloys on the nickel base against the influence of corrosive media, and more particularly concerns the metal-ceramic coatings used for protecting the flow parts of the turbines of turbopump liquid-propellant rocket engines (LRE). The composition for producing the metal-ceramic coating consists of nickel and of oxides of barium, boron, aluminum, cerium and zirconium at the following percentage of components by mass: nickel--36-58, barium oxide--16-19, boron oxide--7-13, aluminum oxide--6-9, cerium oxide--14-19, zirconium oxide--1-2. The coating is produced of a slip, that is applied to the pieces by dipping, spraying or flooding. The slip layers are dried in the flow of hot air. The coating is fired in a furnace in the inert gas medium, argon for example, at a temperature of 1000-1100.degree. C. during 0.5-1 hour. The use of the composition for producing a metal-ceramic coating for the pieces and units of complicated shape made of nickel alloys with a layer of nickel secures their serviceability and reliability at a cyclic action of a high-temperature flow of oxidizing generator gas containing the particles of AMg6 alloy at the temperature of up to 900.degree. C.
