    摘要: A method of producing a honeycomb structure includes a step of forming a ceramic block by bonding a plurality of honeycomb units that have a plurality of cells partitioned by cell walls using a bonding layer, or steps of forming a ceramic block of a single honeycomb unit and providing a coating layer on an outer peripheral portion of the ceramic block. The bonding layer or coating layer is provided as a paste of a bonding material or a coating material including particles of a foaming material having a diameter in a range of approximately 1 μm to approximately 50 μm. The method further includes a step of blowing up the foaming material, and a step of evaporating the foaming material and forming bubble marks having a diameter in a range of approximately 100 μm to approximately 300 μm.

    摘要: The invention comprises a self-lubricating ceramic composite characterized as having a low porosity derived from a mixture of at least one ceramic powder preferably selected from the group consisting of silicon nitride, silicon carbide, zirconia, alumina, zirconium nitride, tungsten carbide, and titanium carbide; a cemetitious binder, effective amounts of at least one metal silicide, and at least one metal oxide. The ceramic powder mixture can be slurried with sufficient amounts of water and subsequently subjected to pressures of about 6.0 to 7.0 MPa in a mold at temperatures of about 125° to 175° C. to form a self-lubricating ceramic composite capable of maintaining hot-hardness temperatures above 750° C. These self-lubricating ceramic composites are particularly useful in the manufacture of high-performance turbine engines, including engine parts, bearings, gears, rotors and in other areas where high-heat lubricating properties of the ceramic composite are required.
