  • Method for forming a carbon deposit inhibiting thermal barrier coating for combustors
    Patent number: 6797332
    Abstract: A method for forming a carbon deposit inhibiting thermal barrier coating for an internal element or component of a gas turbine engine. Such coating includes a layer of thermal barrier material coated onto the surface of an engine component that will be exposed to the flow of burning engine gases. Such coating further includes a layer of carbon deposit inhibiting material coated on top of the layer of thermal barrier material.
    Type: Grant

  • Method of coating silicon carbide fibers
    Patent number: 4923719
    Abstract: This invention relates to a method of coating fibers by contacting the fibers with an organochlorosilane, drying and heating the fibers at a temperature of about 300.degree. to 500.degree. C., thereby coating the fibers. The choice of organochlorosilane and atmosphere under which the heating takes place will determine the composition of the coating.

  • Alumina composite reinforced by zirconia-clad alumina fibers
    Patent number: 4732877
    Abstract: Alumina fibers whose surface is coated with zirconia to retain their identity in an alumina matrix when the mixture is sintered at temperatures needed to form a fully dense ceramic. The resulting fully dense ceramic composite shows the beneficial effects of such reinforcing fibers by having increased crack toughness.

  • Graphite-metal matrix bearings and methods of manufacturing
    Patent number: 4508158
    Abstract: Methods are disclosed for manufacturing graphite fiber metal matrix bearing materials using liquid metal pressure infiltration to achieve a high degree of intimate wetting, contact and infiltration of a compliant metal between and around graphite (carbon) fibers to provide graphite fiber metal matrix bearing material having a predetermined volume percentage of graphite fibers. In one embodiment, graphite fibers are wrapped around a removable cylindrical mandrel and the graphite fiber-wrapped mandrel is inserted into a mold and the mold which contains a liquid compliant metal, such as lead, to cause intimate wetting, contact and infiltration of the compliant metal between and around all of the graphite fibers.
