Abstract

An article having a multiphase composite lubricant coating of a hard refractory matrix phase of titanium nitride dispersed with particles of a solid lubricating phase of molybdenum disulfide is prepared by heating the article to temperatures between 350.degree. and 850.degree. C. in a reaction vessel at a reduced pressure and passing a gaseous mixture of Ti((CH.sub.3).sub.2 N).sub.4, MoF.sub.6, H.sub.2 S and NH.sub.3 over the heated article forming a multiphase composite lubricant coating on the article.

CVD method of forming self-lubricating composites

Patent Besmann, T.M.; Blau, P.J.; Lee, W.Y.; ...

An article having a multiphase composite lubricant coating of a hard refractory matrix phase of titanium nitride dispersed with particles of a solid lubricating phase of molybdenum disulfide is prepared by heating the article to temperatures between 350 and 850 C in a reaction vessel at a reduced pressure and passing a gaseous mixture of Ti((CH{sub 3}){sub 2}N){sub 4}, MoF{sub 6}, H{sub 2}S and NH{sub 3} over the heated article forming a multiphase composite lubricant coating on the article. 1 fig.
CVD method for forming B.sub.i -containing oxide superconducting films

Patent Wessels, Bruce W. (Wilmette, IL); Marks, Tobin J. (Evanston, IL); Richeson, Darrin S. (Evanston, IL); ...

Films of high T.sub.c Bi-Sr-Ca-Cu-O superconductor have been prepared by MOCVD using volatile metal organic precursors and water vapor. The metal organic precursors are volatized along with a bismuth source, such as Bi(C.sub.6 H.sub.5).sub.3, deposited on a heated substrate to form a film, and annealed.

Forming metal-intermetallic or metal-ceramic composites by self-propagating high-temperature reactions

Patent Rawers, James C. (Albany Research Center, Bureau of Mines, Department of the Interior, 1450, Albany, OR 97321); Alman, David E. (Albany Research Center, Bureau of Mines, Department of the Interior, 1450, Albany, OR 97321); Petty, Jr., Arthur V. (Albany Research Center, Bureau of Mines, Department of the Interior, 1450, Albany, OR 97321)

Industrial applications of composites often require that the final product have a complex shape. In this invention intermetallic or ceramic phases are formed from sheets of unreacted elemental metals. The process described in this invention allows the final product shape be formed prior to the formation of the composite. This saves energy and allows formation of shaped articles of metal-intermetallic composites composed of brittle materials that cannot be deformed without breaking.

CVD apparatus and process for the preparation of fiber-reinforced ceramic composites

Patent Caputo, Anthony J. (Knoxville, TN); Devore, Charles E. (Knoxville, TN); Lowden, Richard A. (Powell, TN); ...

An apparatus and process for the chemical vapor deposition of a matrix into a preform having circumferentially wound ceramic fibers, comprises heating one surface of the preform while cooling the other surface thereof. The resulting product may have fibers that are wound on radial planes or at an angle from the radial planes. The fibers can also be precoated with pyrolytic carbon before application of the matrix. The matrix is applied by passing reactant gas through the preform thereof to the other side thereof for the initial deposition of matrix near such other surface of the preform.

Microwave plasma CVD of NANO structured tin/carbon composites

Patent Marcinek, Marek [Warszawa, PL]; Kostecki, Robert [Lafayette, CA]

A method for forming a graphitic tin-carbon composite at low temperatures is described. The method involves using microwave radiation to produce a neutral gas plasma in a reactor cell. At least one organo tin precursor material in the reactor cell forms a tin-carbon film on a supporting substrate disposed in the cell under influence of the plasma. The three dimensional carbon matrix material with embedded tin nanoparticles can be used as an electrode in lithium-ion batteries.
