A coated substrate product is described comprising a substrate and a dielectric coating material comprising carbon, hydrogen, silicon, and oxygen. According to the method, the substrate is processed by plasma cleaning the surface and then depositing a dielectric coating by a suitable plasma process. The coating may contain one or more layers. The substrate may be a rigid material or a thin film or foil. The coated products of this invention have superior dielectric material properties and utility as substrates for the manufacture of rolled or parallel plate capacitors with high energy densities.

Dielectric coatings and use in capacitors

Ion beam process for deposition of highly abrasion-resistant coatings

An abrasion-resistant dielectric composite product is described comprising a substrate and an abrasion wear resistant coating material comprising carbon, hydrogen, silicon, and oxygen and a dielectric material. An improved method is provided for the deposition of highly durable and abrasion-resistant multilayer dielectric antireflective coatings and reflective colored mirror coatings onto plastic lenses such as ophthalmic lenses, safety lenses, sunglass lenses, and sports optics. An adhesion-enhancing polymer layer may be deposited onto the plastic substrate prior to deposition of the abrasion-resistant first coating layer. The multilayer dielectric coating structure consists of a transparent, highly abrasion-resistant first coating, and a second dielectric coating composed of at least one layer of dielectric material. The abrasion-resistant first coating layer is deposited by ion-assisted plasma deposition from mixtures of organosiloxane or organosilazane precursor gases and oxygen, and has the properties of Nanoindentation hardness in the range of about 2 GPa to about 5 GPa, a strain to microcracking greater than about 1.5% and less than about 3.5%, a transparency greater than 85% throughout the visible spectrum, and an abrasion resistance greater than or equal to the abrasion resistance of glass. The preferred method for deposition of the abrasion-resistant first coating layer is plasma ion beam deposition using an organosiloxane precursor gas and oxygen. Optimum abrasion-resistance is obtained when the first coating layer thickness is in the range of about 5 microns to about 20 microns. The thickness, refractive index, and number of the dielectric layers in the second coating are chosen to produce the desired optical effects of either antireflection, or reflected color. Optimum environmental durability and abrasion-resistance is obtained by producing highly dense dielectric coatings by ion beam assisted electron beam evaporation, magnetron sputtering, ion beam assisted magnetron sputtering, ion beam sputtering, and ion-assisted plasma deposition, including plasma ion beam deposition, from precursor gases.

Highly durable and abrasion-resistant dielectric coatings for lenses

The invention provides a thermal print head with a protective coating of silicon-doped diamond-like carbon (Si-DLC) which imparts superior wear resistance, and improved lifetime. The Si-DLC is comprised of the elements C, H, Si and possibly O, N and Ar. The highly wear and abrasion-resistant Si-DLC diamond-like carbon coating is deposited by ion-assisted plasma deposition including direct ion beam deposition and capacitive radio frequency plasma deposition, from carbon-containing and silicon-containing precursor gases consisting of hydrocarbon, silane, organosilane, organosilazane and organo-oxysilicon compounds, or mixtures thereof. The resulting Si-DLC coating has the properties of Nanoindentation hardness in the range of approximately 10 to 35 GPa, thickness in the range of approximately 0.5 to 20 micrometers, dynamic friction coefficient of less than approximately 0.2, and a silicon concentration in the range of approximately 5 atomic % to approximately 40 atomic %. Optimum performance is obtained when the Si-DLC coating hardness is in the range of approximately 15 to 35 GPa, preferably in the range of about 15 GPa to about 19 GPa, and the Si-DLC layer thickness is in the range of approximately 2 micrometers to approximately 10 micrometers, dynamic friction coefficient of less than approximately 0.15, and a silicon concentration in the range of approximately 10 atomic % to 30 atomic %, preferably in the range of about 15 atomic percent to about 24 atomic percent.

Highly wear-resistant thermal print heads with silicon-doped

An ion beam deposition method is provided for manufacturing a coated substrate with improved wear-resistance, and improved lifetime. The substrate is first chemically cleaned to remove contaminants. Secondly, the substrate is inserted into a vacuum chamber onto a substrate holder, and the air therein is evacuated via pump. Then the substrate surface is bombarded with energetic ions from an ion beam source supplied from inert or reactive gas inlets to assist in removing residual hydrocarbons and surface oxides, and activating the surface. After sputter-etching the surface, a protective, wear-resistant coating is deposited by plasma ion beam deposition where a portion of the precursor gases are introduced into the ion beam downstream of the ion source, and hydrogen is introduced directly into the ion source plasma chamber. The plasma ion beam-deposited coating may contain one or more layers. Once the chosen coating thickness is achieved, deposition is terminated, vacuum chamber pressure is increased to atmospheric and the coated substrate products having wear-resistance greater than glass are removed from the chamber. These coated products may be ceramics, architectural glass, analytical instrument windows, automotive windshields, and laser bar code scanners for use in retail stores and supermarkets.

The product has greatly improved wear resistance for severe abrasive environments and comprises a substantially optically transparent substrate, one or more chemically vapor deposited interlayers bonded to the substrate and a chemically vapor deposited outer layer of optically transparent or substantially optically transparent hard and low friction material bonded to the interlayer and away from the substrate.

Abrasion wear resistant coated substrate product

An abrasion wear resistant coated substrate product is described comprising a substrate and an abrasion wear resistant coating material comprising carbon, hydrogen, silicon, and oxygen. The abrasion wear resistant coating material has the properties of Nanoindentation hardness in the range of about 2 to about 5 GPa and a strain to microcracking greater than about 1% and a transparency greater than 85% in the visible spectrum. The coated products of the present invention are suitable for use in optical applications such as ophthalmic lenses or laser bar code scanner windows. In the method for making the products, the substrate is first chemically cleaned to remove contaminants. In the second step, the substrate is inserted into a vacuum chamber, and the air in said chamber is evacuated. In the third step, the substrate surface is bombarded with energetic ions and/or reactive species to assist in the removal of residual hydrocarbons and surface oxides, and to activate the surface. After the substrate surface has been etched, a protective, abrasion-resistant coating is deposited by plasma or ion beam deposition. Once the chosen thickness of the coating has been achieved, the deposition process on the substrates is terminated, the vacuum chamber pressure is increased to atmospheric pressure, and the coated substrate products having improved abrasion-resistance are removed from the vacuum chamber.
