One of the latest ideas in surface engineering is the deposition of new kinds of coatings, called adaptive or chameleon. Based on literature review, the different mechanisms of the adaption of such coatings depend on the applied ranges of temperature and loads were compared. Moreover, the main directions of development of adaptive coatings were also presented. The paper includes results of single coatings, a-C and MoS2, as well composite coatings, a-C/MoS2, in which the mechanism of adaptation was expected. Indentation tests were carried out to determine nanohardness and elasticity modulus. The adhesion of coatings to steel substrates was studied by scratch testing, and tribological properties were studied using a high-temperature ball-on disc tribometer and tests results conducted at room temperature and at elevated temperatures up to 300°C. Results showed that composite coating, a-C/MoS2, can work over the entire range of temperatures with a low coefficient of friction 0.02–0.1 and wear index of 0.07–0.47•10–6 mm3/Nm. Whereas, a-C and MoS2 coatings exhibited a low coefficient of friction and a high wear resistance at low and high temperatures, respectively.

W pracy przedstawiono nowy kierunek w inżynierii powierzchni tworzenia powłok adaptacyjnych, zwanych także kameleonowymi. Na podstawie analizy literatury zestawiono różne mechanizmy adaptacji powłok, w zależności od zakresu stosowanych temperatur pracy i kierunki rozwoju takich powłok. Przedstawiono także wyniki badań własnych dla powłok pojedynczych a-C i MoS2 i na ich tle wyniki dla powłok a-C/MoS2, w których spodziewano się mechanizmu adaptacji. Przeprowadzono testy indentacyjne, z których wyznaczono ich nanotwardość i moduł sprężystości. Analizowano także adhezję powłok do podłoży stalowych przy użyciu testu zarysowania. Testy tribologiczne przeprowadzono w temperaturze pokojowej oraz w podwyższonej do 300°C. Uzyskane wyniki wykazały, że w odróżnieniu do powłok a-C i MoS2 powłoki a-C/MoS2 mogą pracować w całym zakresie badanych temperatur. Wskazują na to niskie wartości współczynnika tarcia 0,02–0,1 i wskaźnika zużycia 0,07–0,47•10–6 mm3/Nm.
