FIELD: articles with high degree of cleanness of surface operating under differential pressure and in chemical corrosive mediums. SUBSTANCE: method involves coating surface of articles with composition made on the base of fine-dispersion powder filler of heat-resistant nonmetallic material prior to or after additional compaction of articles by pyrolytic material from gaseous phase under reduced partial pressure of working gas. The filler can be represented by group of oxides, nitrides, carbides, carbon or chemically compatible mixtures of these materials and shrinkageless non-foaming binding component. Then coating is fixed on surface of article by its saturation with gaseous phase pyrolytic material which is chemically compatible with powder filler material. Additional precipitation of gaseous phase pyrolytic coating material on article surface is quite possible. EFFECT: enhanced operating reliability. 2 cl
