A part of the coating surface was covered by the copper foil mask to measure its thickness afterwards. The properties and characteristics of the sample surface microtopography before and after coating deposition are studied by the atomic-force microscopy (AFM). The technique for the high-precision determination of the coating thickness using the results of the AFM scanning of the transition area between the substrate and the coating on the sample surface is described and applied. The calculated uncertainty of the measured value of thickness is significantly less than in other methods. Mechanical properties of the coating are measured by the instrumental indentation method; the significance of an accurate determination of the correct thickness for measuring the coating characteristics by the indentation technique is shown.</p></abstract><trans-abstract xml:lang="ru"><p>Проведено исследование покрытия из нитрида титана (TiN), нанесенного методом ионно-плазменного напыления на подготовленную поверхность образца стали 40Х. Для измерения толщины покрытия часть поверхности закрывалась маской из медной фольги. Свойства и характерные особенности микрорельефа поверхности образца до и после нанесения покрытия исследовались с помощью атомно-силовой микроскопии (АСМ). Описана и применена методика определения толщины покрытия с высокой точностью на основе результатов АСМ сканирования переходной между подложкой и покрытием зоны на поверхности образца. Вычисленная неопределенность измеренного значения толщины значительно меньше, чем при использовании других методов. Методом инструментального индентирования измерены механические свойства покрытия; показана важность точного определения толщины для корректного измерения характеристик покрытия методом индентирования.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>шероховатость</kwd><kwd>твердость</kwd><kwd>модуль Юнга</kwd><kwd>измерение толщины покрытия</kwd><kwd>инструментальное индентирование</kwd><kwd>сканирующая зондовая микроскопия</kwd><kwd>roughness</kwd><kwd>hardness</kwd><kwd>Young’s modulus</kwd><kwd>coating thickness measurement</kwd><kwd>instrumented indentation</kwd><kwd>scanning probe microscopy</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">Zhang, S.
