摘要： This invention relates to novel macrocomposite bodies. More particularly, it has been discovered that the properties of a ceramic, ceramic matrix composite or metal matrix composite body may be improved by providing on at least a portion of the surface of the body a polymer-based material which serves to protect the body from damage which might occur in the absence of the polymer-based material. One particularly preferred embodiment of the present invention is a macrocomposite shaft sleeve. Another particularly preferred embodiment is a macrocomposite apex used in a hyrocyclone separator.

摘要： A method for producing a self-supporting ceramic composite structure comprising a ceramic matrix embedding a filler, includes oxidizing a parent metal to form a polycrystalline material comprising the oxidation reaction product of the parent metal and, optionally, one or more metallic constituents. The method includes heating the parent metal to provide a source of molten parent metal and a reservoir of molten metal which is in communication with the parent metal and contacting the molten parent metal with a permeable bedding of filler. The molten parent metal reacts with the oxidant to form the oxidation reaction product and is replenished by the reservoir as the reacting continues for a time sufficient to grow the oxidation reaction product to a desired extent and thereby embed at least a portion of the bedding of filler within the oxidation reaction product to form the ceramic composite structure. The bedding of filler may have any suitable shape, including that of a hollow body, the interior of which is contacted by the molten parent metal to grow the oxidation reaction product through the shaped, hollow body of filler.

摘要： There is disclosed a method for producing a self-supporting ceramic body by oxidation of a molten precursor metal with a vapor-phase oxidant to form an oxidation reaction product and inducing a molten flux comprising said molten precursor metal through said oxidation reaction product. A second metal is incorporated into said molten flux during the oxidation reaction. The resulting ceramic body includes sufficient second metal such that one or more properties of said ceramic body are at least partially affected by the presence and properties of said second metal in the metallic constituent.

摘要： There is disclosed a method of producing a self-supporting ceramic composite body having therein at least one cavity which inversely replicates the geometry of an expendable pattern. The method includes the steps of surrounding the expendable pattern with a filler material to thereby form a filled cavity within the filler material. The expendable pattern is chemically or physically removed from the filler material and a quantity of a parent metal is put into the cavity. The parent metal is heated to a temperature above its melting point and an oxidation reaction process begins whereby the oxidation reaction product infiltrates and embeds the surrounding filler material. Excess filler material and/or excess parent metal are removed, thus resulting in a self-supporting ceramic composite body having a cavity in the shape of the expendable pattern.
