Abstract: In S102, after preforming a pressed powder member by compressing metal powder filled in a press-forming portion, the pressed powder member and metal member are slid to each other in S103. In S104, after temporarily joining the pressed powder member and the metal member by further pressurizing the powder member, the temporary joined pressed powder member and the metal member are sintered in a sintering furnace, and the pressed powder member and the metal member are joined by sintering diffusion in S105. Thereby, joining areas between the pressed powder member and the metal member are increased, and it is possible to improve a joining strength between the pressed powder member and the metal member.
Abstract translation: 在S102中，在S103中，通过压缩填充在压制成形部中的金属粉末预压成形粉末构件后，压制粉末构件和金属构件相互滑动。 在S104中，通过对粉末构件进一步加压而暂时接合压粉构件和金属构件，将临时压接粉末构件和金属构件在烧结炉中烧结，将压制粉末构件和金属构件接合在一起 烧结扩散在S105。 因此，压粉构件和金属构件之间的接合区域增加，并且可以提高压制粉末构件和金属构件之间的接合强度。

Abstract: In a manufacturing method of a soft magnetic member, a material powder that includes ferrous particles and an organic layer formed on a surface of each of the ferrous particles is prepared. The organic layer contains at least one element selected from the group consisting of Si, Mg, Ti, and V. The material powder is compacted to form a green compact, and the green compact is induction-heated with a frequency of 100 kHz or higher to form an insulation layer made of an oxide containing the element on the surface of each of the ferrous particles.
