Толщина полученных детонационных покрытий NiCr-Al составляла 214-288 мкм. Когда ствол заполнен взрывоопасной газовой смесью на 40%, покрытие получается недостаточно плотным с заметными границами между отдельными частицами, что может быть результатом недостаточного нагрева и ускорения частиц распыляемого порошка. Более высокие значения микротвердости были получены при заполнении ствола на 50%. Результаты трибологических испытаний покрытий показали, что покрытие, нанесенное при объеме заполнения детонационного ствола взрывчатой смесью до 60%, имеет меньшую степень износа, чем другие покрытия. Видно, что потеря массы при 50% от объема заполнения детонационного ствола меньше, чем у других покрытий. </p></abstract><trans-abstract xml:lang="en"><p>This paper discusses the results of studies of the properties of Ni-Cr-Al wearresistant detonation coatings obtained at different values of the volume of filling the detonation barrel with an explosive acetylene-oxygen mixture. The thickness of the obtained detonation coatings NiCr-Al was 214-288µm. When the barrel is filled with an explosive gas mixture of 40%, the coating is not dense enough, with noticeable boundaries between individual particles, which may be the result of insufficient heating and acceleration of the particles of the sprayed powder. Higher values of microhardness were obtained at 50% filling of the barrel. The results of tribological tests of coatings have shown that the coating applied when the volume of filling the detonation barrel with an explosive mixture is up to 60 %, has a lower wear rate than other coatings. Visible that the mass loss at 50% of the detonation barrel filling volume is less than other coatings. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>детонационное напыление</kwd><kwd>NiCr-Al покрытия</kwd><kwd>структура</kwd><kwd>износостойкость</kwd><kwd>сталь 12Х1МФ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>detonation spraying</kwd><kwd>NiCr-Al coatings</kwd><kwd>structure</kwd><kwd>wear resistance</kwd><kwd>steel 12Kh1MF</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">Yu-Juan Zhang, Xiao-Feng Sun , Heng-Rong Guan etc. 10500C isothermal oxidation behavior of detonation gun sprayed NiCrAlY coating // Surface and Coatings Technology. – 2002. – V.161. –</mixed-citation><mixed-citation xml:lang="en">Yu-Juan Zhang, Xiao-Feng Sun , Heng-Rong Guan etc. 10500C isothermal oxidation behavior of detonation gun sprayed NiCrAlY coating // Surface and Coatings Technology. – 2002. – V.161. –</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">№ 2-3. – Р. 302-305.</mixed-citation><mixed-citation xml:lang="en">№ 2-3. – Р. 302-305.</mixed-citation></citation-alternatives></ref><ref id="cit3"><label>3</label><citation-alternatives><mixed-citation xml:lang="ru">Zhang Y.J., Sun X.F., Zhang Y.C. etc. A comparative study of DS NiCrAlY coating and LPPS NiCrAlY coating // Mater.
