Abstract

FIELD: metal protection. SUBSTANCE: protecting layer on metallic walls in combustion units, heat-exchangers or similar arrangements is created by means of applying powder of metallic, carbide, oxidoceramic, silicide materials or mixtures thereof by means of plasma spraying. Wall surface is first conferred roughness and basic material is activated. Immediately thereafter powder is applied at room temperature and in atmosphere conditions. The powder make-up is preliminarily chosen such that tension, determined with use of heat-expansion coefficients of basic material and tested specimens prepared from various powders for boundary zone between basic material and applied layer, were a temperature function in unloaded state (room temperature) of tensions in the range from 50 to 800 N/sq.mm, preferably 500-800 N/sq.mm, which in a specified loaded temperature zone is largely reduced to zero or has insignificant compression stress. EFFECT: achieved needed wall protection.
