Metal Oxide Containing Coating Patents (Class 427/255.19)
  • Patent number: 6268019
    Abstract: The present invention concerns the deposition of fluorine modified, titanium dioxide films (TiO2) onto hot glass by atmospheric pressure chemical vapor deposition (APCVD) using TiCl4 vapor. The invention is also suitable for depositing other metallic oxide films from their metallic halides such as SnCl4, GeCl4, and VCl4. The present invention provides a process that deposits a novel, fluorine modified, titanium dioxide film (TiO2) onto hot glass by atmospheric pressure chemical vapor deposition using TiCl4 vapor. The process uses injection of TiCl4 into a hot, nonoxygen containing carrier gas and blends the carrier gas and TiCl4 vapor with an oxygen containing gas stream containing a haze reducing quantity of a fluorine containing compound before contacting a surface of hot glass with the blended mixture. The process is capable of depositing a fluorine modified, TiO2 film at deposition rates exceeding 900 Å per second. The crystalline phase of the fluorine modified film is essentially anatase.

  • Patent number: 6238738
    Abstract: A chemical vapor deposition process for laying down a tin or titanium oxide coating on a glass substrate through the use of an organic oxygen-containing compound and the corresponding metal tetrachloride. The organic oxygen compound is preferably an ester having an alkyl group with a &bgr; hydrogen in order to obtain a high deposition rate. The resulting article has a tin or titanium oxide coating which can be of substantial thickness because of the high deposition rates attainable with the novel process, and, in the case of titanium oxide coating possesses a desirable refractive index greater than 2.4. The coating growth rates resulting from the method of the present invention may be at least 130 Å per second.

  • Patent number: 6183884
    Abstract: A metallic article includes a bond coating and a ceramic thermal barrier coating on the bond coating. The ceramic thermal barrier coating includes a plurality of columnar grains, which extend perpendicularly to the surface of the metallic article. Each columnar grain includes a plurality of layers. Some of the layers include sub-grains extending at an acute angle to the surface of the metallic article to form voids between adjacent sub-grains. The voids are arranged at an acute angle to the surface of the metallic article and reduce the thermal conductivity of the ceramic thermal barrier coating. Some of the layers include sub-grains extending perpendicularly to the surface of the metallic article to provide erosion resistance.

  • Patent number: 6168845
    Abstract: A new method for making patterned magnetic storage media with magnetic and substantially non-magnetic zones utilizes a selective oxidation processes. Selective oxidation is achieved by subjecting a magnetic layer to an oxygen plasma through voids in a patterned mask. A high resolution patterned mask is made by embossing and reactive ion etch processes. The method is used to fabricate patterned magnetic disks media with alternating magnetic and non-magnetic zones ranging from 10 to 1000 Nanometers in width. Magnetic storage disks produced by this method have high-bit densities, minimal topography and reduced signal noise.
