摘要： PURPOSE:To produce the titled ceramics having excellent strength and toughness, by applying electromagnetic force to a slurry containing nonconductive ceramics and electroconductive SiC fiber, molding the ceramics and then sintering the moldings. CONSTITUTION:A mixed raw material of nonconductive ceramics powder (e.g. Al2O3 powder) with 50-60vol.% electroconductive SiC fiber is dispersed to provide slurry 1, which is then poured into an air permeable mold 2 supported by a mold frame 3 and electricity is sent to a coil 8 to magnetize iron core and 100-10,000 gauze line of magnetic force is applied to the direction linking iron core 7a with iron core 7b to orientate SiC fiber in one direction and inside of discharge box 5 is evacuated through a discharge pipe 6 connected to a vacuum pump and a solvent is removed through the mold and air permeable hole 4 to provide the ceramic moldings mixed by nonconductive ceramics powder and electroconductive SiC fiber. Then the moldings are sintered in an inert atmosphere at 1,600-1,800 deg.C.

摘要： PURPOSE:To enable production of a sound product having an optional shape in a short time, by injecting a slurry of ceramics powder and fibers in to an organic mold, sucking and removing a solvent just after the injection, simultaneously calcining a molded product with the mold and applying a hot isotropic pressure. CONSTITUTION:For example, a mixed raw material of Si3N4 powder with SiC whiskers is dispersed in water and the resultant slurry 1 is then cast into an organic mold 2 using an organic polymer as a binder. The interior of a gas discharge box 5 is then directly sucked through a vent pipe 6 connected to a vacuum pump to discharge the water in the slurry through the porous mold 2 and vent holes 4 of a molding flask 3. The mold 2 is then taken out of the molding flask 3 and calcined in pressurized N2 atmosphere in a sintering furnace to collapse and remove the mold 2 and simultaneously afford a fiber-reinforced ceramics calcined compact, which is subsequently treated and finished in N2 under hot isotropic pressure.

摘要： PURPOSE:To improve an anti-wear characteristic and a heat-resistant shock characteristic by a method wherein a main body of flow regulator removably inserted into main bodies of a plurality of stage nozzles is formed by a chromeum-nickel steel and a ceramics is attached to a surface part of the flow regulator plate with a fixing member of chromeum-nickel-molybdenum steel. CONSTITUTION:As a material of a main body 3 of flow regulator plate, a chromeum- nickel steel containing more than 23% of chromeum is used in consideration of an anti-oxidation characteristic, a hot temperature strength and a thermal shock characteristic. A rectangular plate-like ceramics 4 is attached to a rear part 3b of the flow regulator plate showing an excessive wear due to fine powder coal. A fixing of the fixing member 11 to the main body 3 of the flow regulator is performed by a stud welding method which is used in a general metallic material welding process. The fixing member 11 is made of chromeum-nickel-molybdenum steel and so a clearance machining with the ceramic fixing hole under a mechanical work before an aging hardening in a hot temperature heating operation can be performed. Since the main body of the flow regulator plate can be extended, its crack can be prevented and further an excessive hard ceramics is fixed with the fixing member to a surface of the rear part showing erosion, so that it is possible to improve an anti-wear characteristic.
