The possibility of fabrication of granulate based on an alloy of the Fe – Cr – Co system with reduced (7 – 10%) cobalt content for synthesizing permanent magnets by the MIM process is considered. A multicomponent granulate composition (polyformaldehyde, high-pressure polyethylene, stearic acid, beeswax) of spherical powders of the Fe – Cr – Co alloy with reduced cobalt content is produced by gas sputtering (average particle diameter 4.2 μm, degree of polydispersity 0.75). The microstructure of the granulate and its granulometric composition are studied. The characteristics of the granulate (the mean diameter of the particles, their morphology and degree of polydispersity) exceed qualitatively the characteristics of the Catamold 42CrMo4 high-quality granulate produced by the BAFS Company.

用降低钴含量的 Fe-Cr-Co 合金制备颗粒，用于通过 MIM 工艺合成永磁体

考虑了基于 Fe-Cr-Co 系统合金制造颗粒的可能性，钴含量降低（7-10%），用于通过 MIM 工艺合成永磁体。钴含量降低的 Fe-Cr-Co 合金球形粉末的多组分颗粒组合物（聚甲醛、高压聚乙烯、硬脂酸、蜂蜡）是通过气体溅射生产的（平均粒径 4.2 μm，多分散度 0.75）。研究了颗粒的微观结构及其粒度组成。颗粒的特性（颗粒的平均直径、它们的形态和多分散程度）在质量上超过了 BAFS 公司生产的 Catamold 42CrMo4 优质颗粒的特性。
