摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of an electromagnetic member capable of easily forming a coil, where a conductor is wound around a core, without damaging the insulation coating of the conductor, and to provide the electromagnetic member.
SOLUTION: The coil wound around the conductor having the insulating coating is prepared. Then, the coil is molded by resin to a cylindrical body for forming a resin mold body. The resin mold body is arranged in a mold and magnetic powder is filled in the upper, lower, and inner-periphery portions of the resin molding body, thus obtaining a press body, where the core made of magnetic powder and the resin mold body are formed in one piece. Then, the resin of the resin mold body in the press body is removed. The coil, molded by resin, is subjected to pressure forming in the mold with the magnetic powder, in advance, thus allowing a mold resin to prevent the insulating coating of the conductor coming into direct contact with the magnetic powder and hence preventing the insulating coating from being damaged.

摘要： PROBLEM TO BE SOLVED: To provide a cemented carbide having excellent strength and thermal crack resistance, to provide a coated cutting tool using the cemented carbide as a base material, and to provide a method for producing the coated cutting tool. SOLUTION: Disclosed is a cemented carbide in which WC particles are bonded with a bonding phase including Co, and, regarding a region composed of the bonding phase in the cross-section, at least either condition that the Σ3 crystal grain boundary length per 100 square micron is 0.3 to 30 μm or that the ratio of the Σ3 crystal grain boundary length to the whole crystal grain boundary length per 100 square micron is 0.03 to 3% is satisfied. Since the Σ3 crystal grain boundary length satisfies the above specified range, the sliding of an atomic plane caused by the inconsistency of crystals is hard to occur, thus the cemented carbide has excellent plastic deformation resistance, and also, by introducing strains or the like into the grain boundaries, its strength and toughness can be improved.
