В процессе эксплуатации такие покрытия подвергаются воздействию потока энергетических частиц. В представленной работе изучено влияние облучения протонами на механические, структурные и оптические свойства покрытия TiAlN, полученного методом магнетронного распыления. Показано, что облучение протонами дозой 5 · 1016 ион/см2 приводит к увеличению нанотвердости и модуля Юнга выше уровня сверхтвердости, тогда как дальнейшее увеличение дозы облучения (до 2 · 1017 ион/см2 ) приводит к уменьшению данных величин. Методом профилометрии продемонстрировано сглаживание поверхности после облучения. Показано, что облучение протонами приводит к увеличению зеркального отражения. Диффузное отражение увеличивается в меньшей степени и только после облучения относительно низкими дозами протонов ((2–5)· 1016 ион/см2 ).</p><p> </p></abstract><trans-abstract xml:lang="en"><p>Titanium aluminium nitride (TiAlN) is a promising material for space application as protective, radiation-resistance coatings. During the operation in space such coatings are exposed to the flux of energetic particles. We present the results of the proton irradiation effect on the mechanical, structural, and optical properties of the TiAlN coating deposited by reactive magnetron sputtering. The irradiation with fluence of 5 · 1016 ion/cm2 results in an increase of Young՚s modulus and nanohardness above the superhard level, while a further fluence increase (up to 2 · 1017 ion/cm2 ) results in a decrease of these parameters. Surface smoothing after proton irradiation has been demonstrated by profilometry. It is shown that irradiation with protons results in an increase of specular reflectance. Diffuse reflectance increases to a lesser extent and only after irradiation with relatively low proton fluences ((2–5)· 1016 ion/cm2 ).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>нитрид титана-алюминия</kwd><kwd>нанотвердость</kwd><kwd>модуль Юнга</kwd><kwd>профилометрия</kwd><kwd>зеркальное и диффузное отражение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>titanium aluminium nitride</kwd><kwd>nanohardness</kwd><kwd>Young’s modulus</kwd><kwd>profilometry</kwd><kwd>specular and diffuse reflectance</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">Yamamoto, K.
