Method of fabricating silicon carbide coatings on graphite surfaces

Patent Varacalle, Jr., Dominic J. (Idaho Falls, ID); Herman, Herbert [Port Jefferson, NY]; Burchell, Timothy D [Oak Ridge, TN]

The vacuum plasma spray process produces well-bonded, dense, stress-free coatings for a variety of materials on a wide range of substrates. The process is used in many industries to provide for the excellent wear, corrosion resistance, and high temperature behavior of the fabricated coatings. In this application, silicon metal is deposited on graphite. This invention discloses the optimum processing parameters for as-sprayed coating qualities. The method also discloses the effect of thermal cycling on silicon samples in an inert helium atmosphere at about 1600.degree.C. which transforms the coating to silicon carbide.

Coating formulation and method for refinishing the surface of surface-damaged graphite articles

Patent Ardary, Zane L [Lenoir City, TN]; Benton, Samuel T [Knoxville, TN]

The described development is directed to a coating formulation for filling surface irregularities in graphite articles such as molds, crucibles, and matched die sets used in high-temperature metallurgical operations. The coating formulation of the present invention is formed of carbon black flour, thermosetting resin and a solvent for the resin. In affixing the coating to the article, the solvent is evaporated, the resin cured to bond the coating to the surface of the article and then pyrolyzed to convert the resin to carbon. Upon completion of the pyrolysis step, the coating is shaped and polished to provide the article withmore »« less

Composition and method for brazing graphite to graphite

Patent Taylor, Albert J [Ten Mile, TN]; Dykes, Norman L [Oak Ridge, TN]

The present invention is directed to a brazing material for joining graphite structures that can be used at temperatures up to about 2800.degree. C. The brazing material formed of a paste-like composition of hafnium carbide and uranium oxide with a thermosetting resin. The uranium oxide is converted to uranium dicarbide during the brazing operation and then the hafnium carbide and uranium dicarbide form a liquid phase at a temperature about 2600.degree. C. with the uranium diffusing and vaporizing from the joint area as the temperature is increased to about 2800.degree. C. so as to provide a brazed joint consisting essentiallymore »« less

Method for producing dustless graphite spheres from waste graphite fines

Patent Pappano, Peter J [Oak Ridge, TN]; Rogers, Michael R [Clinton, TN]

A method for producing graphite spheres from graphite fines by charging a quantity of spherical media into a rotatable cylindrical overcoater, charging a quantity of graphite fines into the overcoater thereby forming a first mixture of spherical media and graphite fines, rotating the overcoater at a speed such that the first mixture climbs the wall of the overcoater before rolling back down to the bottom thereby forming a second mixture of spherical media, graphite fines, and graphite spheres, removing the second mixture from the overcoater, sieving the second mixture to separate graphite spheres, charging the first mixture back into themore »« less

Systems and methods for forming defects on graphitic materials and curing radiation-damaged graphitic materials

Patent Ryu, Sunmin; Brus, Louis E.; Steigerwald, Michael L.; ...

Systems and methods are disclosed herein for forming defects on graphitic materials. The methods for forming defects include applying a radiation reactive material on a graphitic material, irradiating the applied radiation reactive material to produce a reactive species, and permitting the reactive species to react with the graphitic material to form defects. Additionally, disclosed are methods for removing defects on graphitic materials.
