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 a layered structure comprising a first intermediate layer, said first intermediate layer comprising at least one element of group IVB, group VB or group VIB; a second intermediate layer deposited on top of said first intermediate layer, said second intermediate layer comprising a diamond-like nanocomposite composition; a diamond-like carbon layer deposited on top of said second intermediate layer. The invention further relates to the use of a substrate coated with such a layered structure for high shear and/or high impact applications and to a method to cover a substrate with such a layered structure.

The invention relates to a material including carbon, oxygen, silicon and hydrogen and having a dielectric constant of from about 2.1 to about 3.0 where an FTIR scan of the material includes at least two major peaks signifying Si—CH3 bonding. The invention further relates to a material which has a variable dielectric constant through the thickness of the material. Another aspect of the invention is the method of making the material.
摘要:
The present invention relates to a unique hard coating that provides the necessary characteristics for flat panel display plastic substrates because the coating is amorphous and is comprised of C, H, Si and O. The coating of the present invention is hard, optically transparent, scratch and abrasion resistant and hydrophobic. It is deposited by a low density, low temperature plasma enhanced chemical vapor deposition (PECVD) process and exhibits excellent barrier protection and reduced permeability to moisture, oxygen, helium and other vapors.

摘要:
An intravascular stent (26) has a surface coated with a biocompatible layer. The layer contains a diamond like nanocomposite material. This nanocomposite material comprises carbon, hydrogen, silicon and oxygen as constituent elements. The layer has a stress which is less than 150 MPa in order to ensure a high degree of flexibility and a complete expandability. This lower stress is obtained by the inclusion of relatively large amounts of Si:O bonds. In a preferable embodiment the layer with diamond like nanocomposite material covers the stent (26) for 100%. This is obtained by allowing the stent to move freely along a wire during CAVD deposition.
