| 摘要 |
The invention relates to a composite composed of a plastic substrate and a thin, continuous metal-containing layer, characterised in that the metal-containing layer is ductile, adheres firmly to the plastic substrate, has a thickness of <2 mu m and is composed of a compound corresponding to the formulaMaObCxNyBzwherein: M means one or more metals from the group comprising Ti, Ta, Nb, Zr and Hf, a=0.025 to 0.9 b=0.025 to 0.7 x=0.2 to 0.9 y=0 to 0.7 z=0 to 0.7 a+b+x+y+z=1 provided that the value of a, starting from the substrate surface, increases from a value approximating zero towards to the layer surface, and at least 50% of the carbon atoms at the base of the layer are bound to other carbon atoms by C-C bonds.
