Abstract
A diamond foam article comprises diamond deposited material on a substrate having an open contiguous structure at least partially filled with a filler material. Methods for forming a diamond foam article comprise providing a foam substrate; preparing the foam substrate for diamond deposition; depositing diamond material on the foam substrate by one of several diamond deposition methods; and at least partially filling the diamond foam article with a filler material. Diamond foam articles are bonded to other components.
Claims36
A method for forming a porous diamond article, comprising:
- providing a porous substrate;
- preparing said porous substrate for diamond deposition;
- depositing diamond material on said porous substrate to produce an article having voids therein;
- and
- at least partially filling said voids with a filler material.
A method for forming a diamond foam article, comprising:
- providing a porous substrate;
- preparing said porous substrate for diamond deposition;
- and
- depositing diamond doped with non-diamond material on said porous substrate to produce an article having voids therein.
A method for forming a porous diamond article, comprising:
- providing a porous substrate;
- preparing said porous substrate for diamond deposition;
- depositing diamond material to produce an article having voids therein;
- and
- coating said diamond material with a catalytic material.
A method for preparing a diamond foam material article for soldering or brazing to material capable of being soldered or brazed, comprising:
- providing the diamond foam material article;
- and
- coating a region of said diamond foam material to be soldered to the other material with at least one metal to render the diamond foam capable of sustaining an adhesive solder bond.
A method for soldering a diamond foam material article to a solderable material article, comprising:
- providing the diamond foam material article;
- providing a solderable material article;
- coating a region of said diamond foam material to be soldered to said solderable material article with at least one metal to render the diamond foam capable of sustaining an adhesive solder bond;
- and
- soldering said region of the diamond foam article to said solderable material article.
A method for brazing a diamond foam material article to a brazeable material article, comprising:
- providing the diamond foam material article;
- providing the brazeable material article;
- coating a region of said diamond foam material to be brazed to said brazeable material article with at least one metal to render the diamond foam capable of sustaining an adhesive braze bond;
- and
- brazing said region of the diamond foam article to said brazeable material article in an atmosphere substantially free of oxygen.
A method for bonding a diamond foam material article to a component having at least a region of diamond film at an attachment surface thereof, comprising:
- providing the diamond foam material article;
- providing the component;
- placing said diamond foam material article and said component in contact at said attachment surface in a diamond-growth reaction chamber on a support positioned to permit the formation of a plasma in close proximity with a plane describing the juxtaposition of the diamond foam material article and said attachment surface of said component;
- and
- depositing at least about 0.1 millimeter of diamond so as to fuse said diamond foam material article to said component to form an integral structure.
