Abstract
This invention relates generally to a novel directed metal oxidation process which is utilized to produce self-supporting bodies. In some of the more specific aspects of the invention, a parent metal vapor is induced to react with a solid oxidant to result in the directed growth of a reaction product which is formed from a reaction between the parent metal vapor and the solid oxidant. The inventive process can be utilized to form bodies having substantially homogeneous compositions, graded compositions, and macrocomposite bodies.
Claims27
A method for forming a self-supporting body comprising:
- providing a solid oxidant-containing material;
- providing at least one filler on at least a portion of said solid oxidant-containing material;
- contacting at least one vapor-phase parent metal with at least a portion of said solid oxidant-containing material;
- and
- causing said at least one vapor-phase parent metal and at least a portion of said solid oxidant-containing material to form at least one reaction product on at least a portion of at least one surface of said solid oxidant-containing material, wherein said at least one reaction product embeds at least a portion of said at least one filler.
A method for forming a self-supporting body comprising:
- providing a first solid oxidant-containing material;
- placing at least one different solid oxidant-containing material on at least a portion of said first solid oxidant-containing material;
- contacting at least one vapor-phase parent metal with at least a portion of said first solid oxidant-containing material and said different solid oxidant-containing material;
- and
- causing said at least one vapor-phase parent metal and at least said first solid oxidant-containing material to form at least one reaction product on at least a portion of at least one surface of at least said first solid oxidant-containing material, wherein said at least one reaction product includes at least a portion of said at least one different solid oxidant-containing material or at least one different reaction product formed from said at least one different solid oxidant-containing material.
A method for forming a self-supporting body comprising:
- providing a first solid oxidant-containing material;
- coating at least a portion of said first solid oxidant-containing material with at least one material selected from the group consisting of at least one parent metal powder and at least one different solid oxidant-containing material;
- contacting at least a portion of said coated first said solid oxidant-containing material with a parent metal vapor;
- and
- causing said parent metal vapor to react to form at least one reaction product on at least a portion of at least one surface of said first solid oxidant-containing material, wherein said at least one reaction product includes at least a portion of at least one material selected from the group consisting of said at least one powdered parent metal, said at least one different solid oxidant-containing material and at least one different oxidation reaction product formed from said at least one powdered parent metal or said at least one different solid oxidant-containing material.
