  • Patent number: 8003167
    Abstract: There is provided a method of making a heat treated (HT) coated article to be used in shower door applications, window applications, or any other suitable applications where transparent coated articles are desired. The method may include heat treating a glass substrate coated with at least a layer of or including diamond-like carbon (DLC) or other type of carbon, with a protective film thereon. In certain example embodiments, the protective film may be of or include a layer of or including SnOx prior to HT. Optionally, a release layer of a material such as zinc oxide may be provided between the SnOx and the DLC. Following and/or during heat treatment the SnOx transforms into SnOy (y>x) so that stress is created due to the SnOx to SnOy transition. Then, during quenching, stress relief may occur which causes the layer to buckle, creating cracks which may act as liquid channels that permit the sacrificial film to be easily removed via washing or the like.

    Abstract: A method of creating adherent surface coatings on carbide cutting tools or other workpiece substrates through the development of polycrystalline diamond coatings or composite coatings comprising a refractory metal carbide and polycrystalline diamond is described. The coating is deposited through a sequenced chemical vapor deposition process, first using a specified gas mixture of hydrogen and a refractory metal halide to deposit a base layer of a refractory metal carbide. This step is followed by a second step in which polycrystalline diamond is deposited from a gas mixture comprising a hydrocarbon and hydrogen. Co-deposition of refractory metal carbide and diamond in the second step to create a toughened diamond coating is also contemplated.

  • Publication number: 20080268150
    Abstract: The present invention relates to a film-formation method of a diamond electrode used in an electrolytic processing apparatus and other devices for treating water and waste liquid. This method utilizes CVD such as hot filament CVD including supplying a high-concentration carbon source to form a low-quality thick first diamond film (1) on a substrate at a high rate, and then supplying a low-concentration carbon source to form a high-quality thin second diamond film (2) on the first film at a low rate. This structure can prevent oxidation corrosion due to OH radical and can prevent entry of an electrolytic solution into the film, thereby enhancing durability of the diamond film. The thick first diamond film is formed at a high rate, and the second diamond film is made thin at a low rate. Therefore, a total film-formation time can be short, and a low-cost diamond electrode can be made.
