摘要: Growth characteristics of diamond films synthesized by using a dc arc discharge plasma CVD were studied by means of XRD,SEM and reflection electron diffraction. The results showed that columnar growth of the diamond films was observed, the columns having an average diameter of about 15μm, with sharp and regular base edges. Diamond grains grows on the substrata were initially of uniform polygons. An interfacial transition layer of polycrystalline SiC was observed between the diamond film and Si substrate. Diamond grains grown during the early-stage on W substrate were also uniform, and an interfacial transition layer of polycrystalline WC was observed between the diamond film and the substrate.
