A diamond-like carbon-containing material useful as a coating for electronic devices including field emission devices and color television tubes, the coatings having both low secondary electron emission coefficients of less than unity and electrical resistivity tunable over a range of from about 10e to about 10e .

Electrically tunable low secondary electron emission diamond-like coatings and process for depositing coatings

The invention relates to fluorine-doped coatings which include a diamond-like composition containing carbon, silicon, oxygen, hydrogen, and fluorine on various substrates. Preferred substrates include flexible substrates, precision-edged substrates, and electrosurgical instruments. The present invention also relates to a method of making a substrate coated with a fluorine-doped diamond-like coating which includes positioning the substrate in a vacuum coating chamber and depositing a diamond-like composition containing carbon, silicon, oxygen, hydrogen, and fluorine onto the substrate by co-deposition of clusterless particle beams comprised of ions, atoms, or radicals of the carbon, silicon, oxygen, hydrogen, and fluorine, the mean free path of each particle species being in excess of the distance between its source and the growing particle coating surface of the substrate.

The invention relates to an improved diamond-like nanocomposite composition comprising networks of a-C:H and a-Si:O wherein the H-concentration is between 40% and 80% of the C-concentration and having a coefficient of friction against steel which is smaller than 0.1 in air with a relative humidity up to 90%, or in water. The invention relates also to a process for depositing the composition on a substrate in a vacuum chamber. The composition comprises preferably 30 to 70 at % of C, 20 to 40 at % of H, 5 to 15 at % of Si and 5 to 15 at % of O and can be doped with transition metals.
