Наноструктурные покрытия Ti-Al-C-N формировались методом реактивного магнетронного осаждения из мозаичных мишеней с различным соотношением Al/Ti при температурах подложки 220, 340 и 440 °C. Методами атомно-силовой и растровой электронной микроскопии обнаружено, что варьирование элементного состава приводит к изменению морфологии покрытий Ti-Al-C-N: при соотношении Al/Ti ~ 0,39 пленки имеют столбчато-зернистую структуру без видимых дефектов и низкую шероховатость Sq  (3,30–5,86 нм); при Al/Ti ~ 0,96 пленки показали столбчатую пористую структуру и более высокую шероховатость Sq (8,83–11,07 нм); при Al/Ti ~ 1,71 имели мелкозернистую структуру и наименьшие значения шероховатости Sq  (0,48–1,74 нм). Нагрев подложки от 220 до 440 °C не оказывал значительного влияния на элементный состав Ti-Al-C-N пленок, однако воздействовал на скорость осаждения, шероховатость поверхности и микроструктуру покрытий. По результатам МТТ-теста прямой зависимости между жизнеспособностью фибробластов, шероховатостью покрытий и их элементным составом не обнаружено, однако жизнеспособность клеток и их способность к пролиферации при контакте с поверхностью покрытий Ti-Al-C-N сохранялась.

Nanostructural Ti-Al-C-N coatings were produced by reactive magnetron sputtering at substrate temperatures of 220, 340 and 440 °C using mosaic targets with different Al/Ti ratios. Using atomic-force and scanning electron microscopy, it was found that the variation of the elemental composition leads to a change in the morphology of Ti-Al-C-N coatings: at an Al/Ti ratio of 0.39, the films have a mixed columnar-granular structure with no visible defects and a low roughness (3.30–5.86 nm); at an Al/Ti ratio of ~ 0.96, the films show a porous columnar structure with a higher roughness (8.83–11.07 nm) and for an Al/Ti ratio of ~ 1.71, the films have a fine-grained structure and the smallest roughness values (0.48–1.74 nm). Substrate heating from 220 to 440 °C did not significantly affect the elemental composition of Ti-Al-C-N films, but it affected the deposition rate, surface roughness, and the microstructure of the coatings. MTT-test results showed no relationship between the fibroblasts viability, the coating roughness and the coating elemental composition. However, the cells viability and their ability to proliferate on the Ti-Al-C-N coatings surface were preserved.
