摘要:
Threaded nipple for joining two electrode sections is provided with an integral ridge intermediate its threads for centering the electrodes in coaxial alignment.
摘要:
A method of forming an oxidation resistant aluminum coating on a carbon-carbon composite comprising applying a slurry over the carbon-carbon composite, composed of an aluminum intermetallic in a liquid suspending vehicle including a high char yield adhesive thermoplastic and a glassy carbon, distributing aluminum, in elemental form, over the coated surface and reacting the composite and coating in a furnace.
摘要:
A process for isostatic molding permitting density of the product being molded to be measured and controlled in-situ. The process is carried out by weighing the mold assembly in the fluid medium within the pressure vessel inclusive and exclusive of the powder charge with the latter weight determined by the difference between the weight of the mold assembly outside of the pressure vessel and its buoyant force in the pressure vessel.
摘要:
A fire retardant flexible graphite composite is formed from particles of exfoliated flexible graphite and particles of unexfoliated graphite flake treated with an intercalating agent usually in a desired ratio based upon the strength and desired fire retardant properties of the composite. A wall or floor covering is formed by compressing the composite into a sheet and rolled into a roll.
摘要:
Flexible graphite sheet is made by compressing a mixture of fine particle of intercalated, exfoliated, expanded natural graphite with fine particles of intercalated, unexpanded, expandable particles of natural graphite admixed with small amounts of a phosphorous bearing compound, the unexpanded particles being more finely sized than the expanded particles. The resulting sheet of flexible graphite exhibits improved fire retardant and sealability properties and additionally resistance to oxidation and corrosion.
