Синтез такого материала основан на методе химического осаждения из газовой фазы (CVD). Синтез протекает на внутренней поверхности косвенно нагреваемой до 1450–1570 °C цилиндрической графитовой сборки, через которую пропускаются контролируемые газовые потоки азота, трихлорида бора и углеродсодержащих газов при низком давлении. Реализованная технология на базе разработанной установки позволяет синтезировать пластинки легированного бором пиролитического углерода, отмеченного совокупностью характеристик химической инертности и биосовместимости с высокими значениями твердости, упругости и длительности использования. Представлено исследование морфологии и состава материала, проведенное методами сканирующей электронной микроскопии и рамановской спектроскопии. Материал находит свое применение в качестве створок эндопротезов клапанов сердца на ОАО «Завод «Электронмаш».</p></abstract><trans-abstract xml:lang="en"><p>The article describes a technological set-up and the synthesis methodology of boron-enriched pyrolytic carbon (B-PyC). The chemical vapor deposition (CVD) approach lies in the basis of the methodology. The synthesis occurs on the inner surface of a cylindrical graphite assembly indirectly heated to the temperatures of 1450–1570 °C. Controlled low-density flows of nitrogen, boron trichloride and carbonaceous gases react in the assembly, producing a B-PyC film deposited on the graphite substrate. The set-up has been designed to provide fabrication of B-PyC plates possessing features required for heart valve endoprosthesis: chemical inertia and biocompatibility combined with high hardness, high elasticity, and long operating life. The morphology and chemical composition of the material have been studied by electron scanning microscopy and Raman spectroscopy. The material is used at the “Electronmash Plant” for fabrication of heart valve endoprosthesis leaflets.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пиролитический углерод</kwd><kwd>карбид бора</kwd><kwd>химическое осаждение из газовой фазы</kwd><kwd>высокотемпературный пиролиз</kwd><kwd>эндопротез клапана сердца</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pyrolitic carbon</kwd><kwd>boron carbide</kwd><kwd>chemical vapor deposition</kwd><kwd>high temperature pyrolysis</kwd><kwd>hurt valve endoprosthesis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Актуальные задачи использования композиционных и гибридных материалов на основе различных форм углерода в электромагнитных и биомедицинских приложениях / С.
