“…The dependence obtained in numerical calculation (.ig. 7) was compared with the data of experimental studies [8]. The calculated average friction coefficient was 0.61 and corresponded to an experimental value of 0.63 at the instant of coating fracture (the coating at this point revealed large cracks but escaped separation from the substrate).…”

“…The coating is thus cracked and fractured right up to the transition layer, but complete separation of the coating material does not occur. The obtained images qualitatively correspond to the initial fracture stage of nanostructured coatings on titanium substrates in scratch testing [8].…”

“…Nanoindentation is controlled penetration of a certainly shaped superhard indenter into a flat specimen surface to a depth less than 100 nm under increasing load with continuous measurement of the force P acting on the indenter and its penetration depth h into the material [8]. Sometimes, nanoindentation is termed instrumented indentation.…”

The paper considers 3D movable cellular automata (MCA) models of contact interactions involved in nanoindentation, sclerometry, and tribospectroscopy. The system under study is a titanium substrate with a hardening coating. The substrate and coating materials are both described in the elastoplastic approximation. It is shown that the MCA method of numerical simulation provides correct description of the contact interaction of elastoplastic materials under different types of loads with explicit account for fracture. The possibility to detect damages in material surface layers from friction force estimates is assessed.

“…Отличие в положениях пиков для профи-лей алюминия и титана составляет 10-15 нм. От-метим, что ранее методом оптической эмисси-онной спектроскопии были исследованы нано-слойные покрытия в системах Ti/Al [13], Ti/AlN [14], Cr/CrN [15] и TiC/VC [16]. Высокое разре-шение для покрытий Cr/Ti по глубине было полу-чено благодаря высокоточному подбору параме-тров травления [7,17].…”

“…Since the thickness of each layer varies from several nanometers to micrometers, a self-propagating exothermic reaction can be initiated in these thin film systems and produces larger quantity of heat with a small thermal pulse or an electrical stimulus. In the past two decades, they were usually used as a local heat source for soldering and brazing applications [9][10][11][12], and several classic review articles have summarized their preparation, characterization and self-propagating reaction waves [13][14][15][16]. In addition, Al/Ni multilayer nanofilms possess good exothermic reaction properties which qualify them as a suitable heat source for energetic initiators.…”

This paper exploits an energetic initiator realized by integrating Al/Ni multilayer nanofilms with semiconductor bridge (SCB). The as-deposited nanofilms have been characterized with varied analytical techniques. Results show that distinct nanofilms are sputter deposited in a layered geometry and give a heat of reaction equal to 1134 J/g. The firing tests of the initiators were accomplished using capacitor discharge unit. Results show that the initiators possess several excellent characteristics such as fast ignition time, low power consumption, high output energy and so on. Therefore, Al/Ni multilayer nanofilms are suitable heat source for improving the reliability of SCB initiators.
