研究了超硬碳膜的力学性质、波谱性质及结构性质 ,指出有一种无氢类金刚石膜是由石墨碎片、布基葱和金刚石晶粒以新型的共价键组成的网架结构 ,具有良好的力学性能 .由于石墨碎片中的π键变形 ,石墨碎片和布基葱边缘的不饱和悬键与金刚石晶粒周围的悬键结合成新型的共价键 .金刚石晶粒只能由激发态碳原子在非平衡重组过程中产生 ,而石墨碎片既可以在碳原子重组过程中产生 ,也可以在蒸发石墨过程中产生 .
The mechanical properties, spectral properties and structural properties of the superhard carbon films were investigated. It is pointed out that a hydrogen-free diamond-like carbon film is a network structure composed of novel covalent bonds of graphite fragments, Buji onions and diamond grains. Due to the π bond deformation in the graphite fragments, the unsaturated dangling bonds between the graphite fragments and the budgee edges combine with the dangling bonds around the diamond grains to form novel covalent bonds, and the diamond grains can only be composed of the excited carbon atoms In non-equilibrium reorganization process, and graphite fragments can be generated in the process of reorganization of carbon atoms can also be generated during the evaporation of graphite.
