METHOD FOR OXIDATION DEFENCE OF ARTICLES FROM COMPOSITE CARBON-CONTAINING MATERIAL AND ARTICLE DEFENCED BY THIS METHOD

摘要

FIELD: chemistry.;SUBSTANCE: invention refers to the method for oxidation defence of the article made from composite carbon-containing material and having the residual open inner pores. The said method includes at least one stage of composite material impregnating to depth with the impregnating composition containing at least one metal phosphate in the solution and titanium diboride in the form of the powder with particle size in the range from 0.1 mcm to 200 mcm. The invention refers also to the article obtained by the aforementioned method. Invention is developed in related items of invention formula.;EFFECT: invention provides the article oxidation defence at temperatures more than 1000°C, particularly in the presence of carbon oxidation catalyst and in wet conditions.;10 cl, 12 dwg, 9 ex, 3 tbl
