Оценено влияние рабочих параметров (скорости подачи и ширины канала впрыска порошка) на геометрию потока частиц. Оптическая диагностика лазерной наплавки проведена посредством инфракрасной камеры.</p></abstract><trans-abstract xml:lang="en"><p>Method for determining geometric characteristics of the gas-powder flow in laser powder cladding with the coaxial injection is proposed. Effect of the working parameters of powder feed rate and the channel width on geometry of the particle flow is evaluated. Optical diagnostic of laser cladding by infrared camera, providing information on temperature of the powder in the flow, is performed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>коаксиальная лазерная наплавка</kwd><kwd>диагностика</kwd><kwd>термография</kwd><kwd>газопорошковый поток</kwd><kwd>coaxial laser cladding</kwd><kwd>diagnostics</kwd><kwd>thermography</kwd><kwd>dust laden jets</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">Ion J.
