| 摘 要： | 采用ＳＥＭ，ＦＴ－Ｒａｍａｎ，ＸＲＤ和ＥＤＸＡ对ＣＶＤ金刚石膜自发剥落后的ＹＧ８硬质合金基体表面的形貌、相结构和微区化学成分进行了表征，结果表明，该表面上存在石墨碳相，呈针片状；沉积金刚石膜后基体表面的ＷＣ颗粒显著细化，表层Ｃｏ含量仍很低。 |
| 关 键 词： | 金刚石膜 硬质合金 相结构 形貌 剥落 |

| Abstract: | Morphology, phase structure and micro-area chemical composition of cemented carbide substrate surface after diamond film spontaneously delaminated have been characterized using scanning electron microscope, Fourier transform laser Raman spectrometry, X-ray diffractometer, and energy dispersive X-ray spectroscopy. The results show that there is a needle-like graphite phase on the cemented carbide substrate after diamond film spontaneously delaminated, the WC grains are obviously fined and the cobalt content is still much lower at the surface layer after diamond film deposited. |
| Keywords: | diamond film cemented carbide phase structure morphology |
