    摘要： The invention relates to a method for forming high sp3 content amorphous carbon coatings deposited by plasma enhanced chemical vapor deposition on external surfaces. This method allows adjustment of tribological properties, such as hardness, Young's modulus, wear resistance and coefficient of friction as well as optical properties, such as refractive index. In addition the resulting coatings are uniform and have high corrosion resistance. By controlling pressure, type of diamondoid precursor and bias voltage, the new method prevents the diamondoid precursor from fully breaking upon impact with the substrate. The diamondoid retains sp3 bonds which yields a high sp3 content film at higher pressure. This enables a faster deposition rate than would be possible without the use of a diamondoid precursor.

    摘要： The invention relates to a method for forming high sp3 content amorphous carbon coatings deposited by plasma enhanced chemical vapor deposition on internal surfaces and employing the “hollow-cathode” technique. This method allows adjustment of tribological properties, such as hardness, Young's modulus, wear resistance and coefficient of friction as well as optical properties, such as refractive index. In addition the resulting coatings are uniform and have high corrosion resistance. By controlling pressure, type of diamondoid precursor and bias voltage, the new method prevents the diamondoid precursor from fully breaking upon impact with the substrate. The diamondoid retains sp3 bonds which yields a high sp3 content film at higher pressure. This enables a faster deposition rate than would be possible without the use of a diamondoid precursor.

    摘要： A method of coating at least one exterior surface of at least one workpiece is disclosed. The method may be used for coating inner and outer surfaces of pipes. A hollow workpiece is positioned within a chamber. A spacing between a multi-dimensional interior surface of the chamber and an exterior surface of the workpiece is fixed. Conditions are established to maintain a hollow cathode effect within the spacing and within the hollow workpiece. The conditions include biasing anodes at opposite ends of a hollow cathode effect region, and biasing the interior surface of the chamber and the workpiece as cathodes. The interior surface and the workpiece may be maintained at a common bias voltage or, in at least one embodiment, at differing voltages.

    摘要： In accordance with one embodiment of the invention, a workpiece having a smaller cross sectional dimension (e.g., diameter) is centered within a workpiece having a larger cross sectional dimension, with the workpieces being electrically connected. In this embodiment, surfaces of the two workpieces can be coated simultaneously, either with the same coating material or different coating materials. In another embodiment, holes are located along the length of an internal metal tube which functions as a gas distribution injector and anode holder. A ceramic liner may be placed inside the internal metal tube, with a conductive wire within the ceramic liner. The internal metal tube may be biased as a cathode, while the internal wire is biased as an anode. The hollow cathode effect is applied in all spaces directly adjacent to the surface or surfaces being coated. In some applications, different surfaces being coated are biased at different voltages.
