FIELD: chemistry.
SUBSTANCE: glass-like coating contains layer (31), made in form of intact film of sol-gel material, including matrix, formed by metal polyalkoxylate, in which particles (32) of anisotropic shape are dispersed, and layer has zone (311), in which most particles (32) are inclined at angle α, constituting from 20° to 90° relative to middle plane of film.
EFFECT: invention provides high hardness, thermal resistance and stability to coating peeling.
