品を製造する技術の確立が所望される。Currently, the mainstream method for producing 7% A/77 alloy is to produce an amorphous ribbon in the form of a thin strip by a rapid cooling method. In order to make molten metal amorphous, it is important to have a rapid cooling rate sufficient to prevent the effect of metalloids that inhibit crystallization and crystal orientation. In order to produce amorphous ribbons with commercial value, it is necessary to continuously produce wide, homogeneous ribbons with good dimensional accuracy.So far, centrifugal methods, double-four-roll methods, and single-roll methods have been proposed. has been done. Although there are advantages and disadvantages for each of the three, the single roll method, which facilitates the production of wide ribbons, is currently attracting particular attention. Amorphous electromagnetic parts are manufactured by punching amorphous ribbons and laminating multiple ribbons if necessary, but since amorphous is considerably harder than other materials, it is extremely difficult to establish accurate punching technology. be. Finish grinding is also very rough. In order to avoid the difficulties of such mechanical processing methods, film forming technology using sputtering has been developed for specific fields such as magnetic heads, but the application field is limited and it is difficult to manufacture multi-layered electromagnetic components in general. Missing. If amorphous alloys can be used to manufacture parts of various shapes, new uses for amorphous alloys are likely to be discovered. Thus, it is desired to establish a technique for manufacturing electromagnetic components of various forms without or with minimal use of mechanical processing such as punching.

It has a composition of Co-10at%5i-15at%B. It is preferable to select the most suitable one depending on the intended use of the electromagnetic component. The main material used for core materials is F・-5i-n.
Co-based material is mainly used for the head material. “As mentioned above, the manufacturing method for amorphous alloy powder is
There are two methods: pulverizing the generated amorphous ribbon using a ball mill, etc., quenching centrifugally atomized droplets, spraying gas or liquid jet onto the molten metal, mechanically dividing the molten metal using rotary blades, etc. There is a method that utilizes the cavity silane phenomenon in which molten metal is ejected between refractory rolls and the force applied to the molten metal changes rapidly from positive to negative. Furthermore, JP-A-59-16506 discloses a method for producing powder by using a cooling disk having uneven notches and injecting molten metal directly onto the cooling disk. The amorphous alloy powder used in the present invention may be produced by any of the above methods. A particularly preferred powder form is flakes. This is a book.

These are mixed in the form of a solution or dispersion. By doing this, unlike adding it in the form of a solid resin as in the above-mentioned Japanese Patent Application Laid-Open No. 59-16056, the coating material penetrates between the amorphous alloy powder particles and forms an extremely thin film that surrounds each particle. , can exhibit a good insulating effect. Only when added in the form of a solution or dispersion can the intended purpose be achieved through its penetrating and diluting effects.

It is possible to produce a pressed product having a density of c. The pressing temperature is selected to be below the crystallization temperature of the amorphous alloy and above the softening or flow temperature of the heat-resistant organic material. The crystallization temperature of an amorphous alloy varies depending on the composition of the amorphous alloy, and F.? In the case of l Bl@S 11, the temperature is 530°C. When the heat-resistant organic material is polyimide, its softening temperature is 300-320°C.
