Исследовано влияние параметров процесса и состава напыляемого материала на структуру, состав и механические свойства покрытий. Показано, что увеличение дистанции напыления и скорости подачи напыляемого материала приводит к снижению их плотности. Повышение концентрации легкоплавкого компонента TiO2 обуславливает уменьшение пористости покрытий, а на их твердость заметного влияния не оказывает. Сформированные с минимальной пористостью (П ~ 3,2  %) пламенные покрытия  Al2O3–TiO2  при  измерительном царапании характеризуются когезионным характером разрушения и отсутствием вскрытия подложки при нагрузке на индентор до 90 Н. Коэффициент трения исследуемых покрытий после 2800 об. контртела (44 м пути трения) меняется от 0,2 до 0,78. Это связано с накоплением в материале  покрытия усталостных трещин и его последующим когезионным разрушением через образование крупных фрагментов, играющих роль  абразива.</p></abstract><trans-abstract xml:lang="en"><p>Al2O3–TiO2-based coating specimens were obtained using the method of oxyfuel gas spraying of a flexible cord. The paper studies the influence of process parameters and  composition of the sprayed material on  the structure, composition and  mechanical properties of coatings. It was shown that the increase in spraying distance and  feed rate of the sprayed material leads to reduction in their density. An increased concentration of the  low-melting TiO2 component preconditions a decrease in coating porosity and has no significant effect on its hardness. During measuring scratching, the Al2O3–TiO2 flame coatings formed with minimal porosity (porosity ~ 3,2 %) are characterized by cohesive fracture behavior and no substrate break up at the 90 N load applied to the indenter. The studied coatings show changes in their friction factor from  0,2  to 0,78  after 2800 counterbody revolutions (44  m of rubbing path). This is due to accumulated fatigue cracks in the coating material and  its subsequent cohesive fracture through formation of large fragments that serve as an abrasive.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>газопламенные покрытия</kwd><kwd>напыление гибкого шнура</kwd><kwd>пористость</kwd><kwd>твердость</kwd><kwd>расход напыляемого материала</kwd><kwd>дистанция напыления</kwd><kwd>износостойкость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flame coating</kwd><kwd>flexible cord spraying</kwd><kwd>porosity</kwd><kwd>hardness</kwd><kwd>flow rate of the sprayed material</kwd><kwd>spraying distance</kwd><kwd>wear resistance</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">Балдаев Л.Х., Борисов В.Н., Вахалин В.А., Ганноченко Г.И., Затока А.Е., Захаров Б.М., Иванов А.В., Кудинов В.В., Ярославцев В.М.
