Abstract
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.
