“…e lattice constant of AlN is 0.2491 nm and bigger than the one of TiSiN. When the AlN layer and TiSiN layer grow epitaxial, AlN layer transforms to a face-centered cubic structure under the template effect of the TiSiN layer [22][23][24][25][26][27]. e lattice constant of the TiSiN layer increases and the one of AlN layer decreases at the interface.…”

TiSiN/AlN nanomultilayers with different thicknesses of AlN layer were deposited on 304 stainless steel by magnetron sputtering system. X-ray diffraction, nanoindentation tester, atomic force microscopy, and friction wear tester were used to characterize microstructure and properties of TiSiN/AlN nanomultilayers. The results show that TiSiN/AlN nanomultilayers are face-centered cubic structures and exhibit a strong preferred orientation on (200) plane. The diffraction peaks of TiSIN/AlN nanomultilayer shift to a small angle. When the thickness of the AlN layer is 2 nm, the peak is highest, and the shift degree is biggest. The alternating tension and compression stress fields are formed along the growth direction of TiSiN/AlN nanomultilayers and increase the strength of the namomultilayers. When the thickness of the AlN layer is 2 nm, the maximum hardness and Young’s modulus of TiSiN/AlN nanomultilayers are, respectively, 32.8 GPa and 472 GPa, and the smallest roughness is 33.4 nm. But the friction coefficient is smallest when the thickness of the AlN layer is 1.5 nm.

“…The composition and microstructure of the coating can be controlled by adjusting the sputtering parameters [16,17]. Multilayers prepared by magnetron sputtering not only combine the advantages of the different constituent materials but also have better performance and microstructure compared to single layers of their respective components due to the superhardness effect, quantum effects, and macro-tunneling effects between the nanolayers [18][19][20][21][22]. In addition to resulting in excellent mechanical properties, the formation of multilayer structures can also improve the oxidation resistance at high temperatures through limited intermixing [23][24][25].…”

TiB2/ZrO2 multilayers with different modulation ratios (at a fixed modulation period of 50 nm) ranging from 2:1 to 6:1 were deposited by magnetron sputtering. The oxidation behavior of the as-deposited multilayers was investigated at 600 °C in air. The microstructures, mechanical properties, and oxidation resistance of the multilayers were analyzed and compared. The results indicate that discontinuous oxidation retarded the inward diffusion of oxygen and the outward diffusion of metallic components. The formation of dense (Ti, B)-oxide scale and internally inserted ZrO2 layers in the TiB2/ZrO2 multilayers enhanced the oxidation resistance. Moreover, the oxidation resistance of the multilayers increased as modulation ratio decreased. The hardness and elastic modulus of the TiB2/ZrO2 multilayers were maximized (23.9 and 303.1 GPa, respectively) at the modulation ratio of 6:1. After annealing, the formation of thick ZrO2 layers did not lead to sustained increases in hardness. The maximum hardness and elastic modulus were obtained at the critical modulation ratio of 4:1, and good adhesion strength with the substrate was also observed. The oxidation mechanism and experimental results demonstrate that controlling the modulation ratio of multilayers can produce synergetic enhancements in the oxidation resistance and mechanical properties of multilayers after high-temperature oxidation.
