摘要:
AlN/ZrB2 multilayered coatings were synthesized in a magnetron sputtering system. The extensive measurements were employed to investigate the influence of different nanoscale modulation periods and modulation ratios on microstructure and mechanical properties of the coatings. Analysis of X-ray diffraction, profiler and nanoindention indicated that multilayered coatings possessed much higher hardness and elastic modulus than monolithic AlN and ZrB2 coatings. At the substrate negative bias of -80 V, maximum hardness (34.1 GPa) and elastic modulus (469.8 GPa) were obtained in the multilayer with Lambda = 30 nm and t(AlN):t(ZrB2) = 1:3. This hardest multilayer showed a marked polycrystalline structure with the strong mixture of ZrB2 (001), ZrB2 (100), ZrB2 (101), AlN (100) textures. (C) 2009 Elsevier Ltd. All rights reserved.
