| 英文摘要 | WB2/Cr multilayer films with different modulation ratios (lambda = 1, 3, 5, 7, 12, and 20) were deposited by a combination of direct-current and pulse direct-current magnetron sputtering, and the number of bilayers was fixed at ten. The effect of the modulation ratio on the microstructure, mechanical and tribological properties of the multilayer films was investigated in detail. X-ray diffraction demonstrates that a preferred orientation of WB2 (101) and Cr (110) exists, and WB2 (101) dominates the film's growth with increasing of modulation ratio. The TEM results show that the multilayer films consist of nanograins dispersed in an amorphous matrix in WB2 layers and polycrystalline grains in Cr layers. The hardness increases with the increasing modulation ratio, and the maximum hardness (31.1 GPa) is obtained at lambda = 20. The indentation toughness presents an opposite changing trend, and the maximum indentation toughness (1.264 MPa m(1/2)) is obtained in S1 at lambda = 1 which conforms to the rule of mixture due to the relatively thick bilayer thickness (Lambda = 160-192 nm). The wear mechanism is investigated, and the results suggest that the multilayer film with lambda = 7 possesses the best wear resistance (2.06 x 10(-7) mm(3)/Nm), benefiting from the balance of hardness and indentation toughness. |
