摘要:
A continuous inorganic fiber consisting of Si, N and O has excellent physical, chemical and electrically insulating properties, is superior to carbon fiber in wettability with metal, is low in reactivity with metal, and can be used not only as a reinforcing fiber for fiber-reinforcing type metals and fiber-reinforcing type ceramics, but also in electrical insulating materials and in heat-resistant materials.
摘要:
A method for manufacturing a silicon carbide fiber reinforced glass composite, which comprises either dipping silicon carbide fibers in molten glass in a tank, the molten glass being given wave vibration of 10-30 KHz by a supersonic vibrator provided with a cooling means to unravel the silicon carbide fibers and have the molten glass permeated therebetween, or plasma melt ejecting glass powder onto silicon carbide fibers to obtain a silicon carbide fiber/gass preform, molding the preform into a predetermined form and then subjecting the molded preform to thermal molding thereby to manufacture the silicon carbide fiber reinforced glass composite in the form of a molding.
摘要:
A process for the surface treatment of inorganic fibers for reinforcing titanium or nickel, comprising the steps of coating the surface of inorganic fibers with an aqueous or organic solvent solution containing a titanate, borate, tetralkylammonium hydroxide and, if desired, dextrin and then heat treating the coated fibers at a high temperature in an inert or non-oxidizing atmosphere. In one embodiment, the heat treated inorganic fibers is further subjected to ionic or chemical plating with nickel.
摘要:
A process for producing carbon fibers from various kinds of pitches wherein the calorific values of the pitches are measured and the pitches thereafter subjected to a suitable procedure for producing carbon fibers therefrom depending on their measured calorific value.
摘要:
A process for producing flexible graphite material comprises incorporating expanded graphite material with boric acid, compression molding the resulting mixture and, if desired, heating the resulting molding while under compression. This invention also relates to the flexible graphite material produced by the process.
摘要:
A process for the preparation of a carbon-metal composite material for mechanical sliding members, comprising impregnating a carbon substrate with an alloy comprising copper, nickel or a copper-nickel as a base metal and at least one of titanium, zirconium and silicon as a wetting agent for the carbon. In one embodiment, the alloy further comprises at least one of a third component such as tin, antimony, zinc, manganese, iron, chromium, lead, magnesium and phosphorus.
摘要:
The dispersion of an inorganic high molecular weight graphite fluoride having a formula of (CF)n in a lubricant is improved by the addition of finely divided silica particles. An improved lubricant composed of base oil, graphite fluoride, and silica has excellent physical and chemical properties hitherto unattainable.
摘要:
A DRY LUBRICANT COATING COMPRISING GRAPHITE FLUORIDE POWDER HAVING A LUBRICATING PROPERTY DISPERSED IN A COATING METAL IS ELECTROPHORETICALLY DEPOSITED ON A SUBSTRATE SIMULTANEOUSLY WITH THE ELECTROLYTIC DEPOSITION OF THE COATING METAL. THE GRAPHITE FLUORIDE IS PRODUCED BY REACTING CARBON OR GRAPHITE WITH FLUORINE AT A TEMPERATURE OF LOWER THAN 550*C.
摘要:
A METHOD OF MAKING A COMPOSITE BEARING WHICH COMPRISES MIXING AND MOLDING A SYNTHETIC RESIN, GRAPHITE FLUORIDE, AND A THIRD COMPONENT SELECTED FROM ARTIFICAL GRAPHITE, NATURAL GRAPHITE, AND NON-CRYSTALLINE CARBON.
摘要:
IN A PROCESS FOR THE MANUFACTURE OF A HIGH TENCITY HIGH FLAME-PROOF CARBONIZED FIBER FROM A CELLULOSIC VISCOSE RAYON, A MODIFIED VISCOSE RAYON FIBER HAVING A HIGH DEGREE OF POLYMERIZATION IS USED AS A STARTING CELLULOSIC MATERIAL.
