Abstract
A substrate is coated with a coating system including at least one diamond-like carbon (DLC) inclusive layer(s) using an ion beam deposition technique. Prior and/or during the ion beam deposition of the DLC inclusive layer, the substrate (e.g., glass substrate) is heated to a temperature of from about 100-400 degrees C. so that at least a surface of the substrate is heated when the DLC inclusive layer(s) is deposited thereon via the ion beam deposition technique. This heating may result in improved adherence of a coating system to the underlying substrate.
Claims27
A method of making a coated article comprising:
- providing a glass substrate;
- heating at least a portion of the glass substrate to a temperature of from about 100-400 degrees C.;
- and
- depositing a layer comprising diamond-like carbon (DLC) directly on the glass substrate using an ion beam source and gas comprising carbon and hydrogen in the source, the ion beam source directing an ion beam including carbon ions toward the glass substrate when at least a portion of the glass substrate is at a temperature of from about 100-400 degrees C. so as to form the layer comprising DLC on the glass substrate, wherein at least about 40% of carbon-carbon bonds in the layer comprising DLC that is formed are sp3 carbon-carbon bonds.
A method of making a coated article comprising:
- providing a glass substrate;
- heating at least a portion of the glass substrate to a temperature of from about 100-400 degrees C. for deposition of a layer comprising amorphous diamond-like carbon (DLC);
- and
- depositing the layer comprising amorphous diamond-like carbon (DLC) on the glass substrate using an ion beam source and gas comprising carbon in the source, the ion beam source directing an ion beam including carbon ions toward the glass substrate when at least a portion of the glass substrate is at a temperature of from about 100-400 degrees C. so as to form the layer comprising amorphous DLC on the glass substrate, wherein at least about 40% of carbon-carbon bonds in the layer comprising amorphous DLC that is formed are sp3 carbon-carbon bonds and the layer comprising amorphous DLC has an average hardness of at least about 10 GPa.
