| 英文摘要 | The work is mainly to study the thermal stability including the phase stability, microstructure and tribo-mechanical properties of the AlB2-type WB2 and W-B-N (5.6at.% N) films annealed in vacuum at various temperatures, which are deposited on Si and GY8 substrates by magnetron sputtering. For the WB2 and W-B-N films deposited on Si wafers, as the annealing temperature increases from 700 to 1000 degrees C, a-WB (700 degrees C) and Mo2B5-type WB2 (1000 degrees C) are successively observed in the AlB2-type WB2 films, which show many cracks at the temperature 800 degrees C resulting in the performance failure; by contrast, only slight -WB is observed at 1000 degrees C in the W-B-N films due to the stabilization effect of a-BN phase, and the hardness increases to 34.1GPa first due to the improved crystallinity and then decreases to 31.5GPa ascribed to the formation of -WB. For the WB2 and the W-B-N films deposited on WC-Co substrates, both the WB2 and W-B-N films react with the YG8 (WC-Co) substrates leading to the formation of CoWB, CoW2B2 and CoW3B3 with the annealing temperature increasing to 900 degrees C; a large number of linear cracks occur on the surface of these two films annealed at 800 degrees C leading to the film failure; after vacuum annealing at 700 degrees C, the friction performance of the W-B-N films is higher than that of the deposited W-B-N films, while the wear resistance of the WB2 films shows a slight decrease compared with that of the deposited WB2 films. |
